Q2.Match the type of motion in Column I with the corresponding characteristic of its x – t graph in Column II.

(A) 1 -Q, 2- R, 3- S, 4- P

(B) 1- S, 2- P, 3- Q, 4- R
(C) 1 -Q, 2- P, 3- S, 4 -R

(D) 1- R, 2- S, 3- P, 4 -Q

Answer : (A) 1–Q, 2–R, 3–S, 4–P

Q3.The horizontal component of a projectile’s velocity, in the absence of air resistance:
(A) Continuously increases throughout its flight path.
(B) Continuously decreases until it reaches its maximum height.
(C) Remains constant throughout its flight path.
(D) Becomes zero at the peak of its trajectory.

Answer: C) Remains constant throughout its flight path.

Explanation:

In projectile motion (neglecting air resistance):

The only force acting is gravity, which acts vertically downward.
There is no horizontal force acting on the projectile.
Therefore, horizontal acceleration = 0.

Since acceleration in the horizontal direction is zero: v_x=u_x=constant

Q4.A bird weights 2N sitting inside a cage of weight 1 N . If it starts flying then what is weight of bird and cage assembly?
(A ) 1.5 N B ) 3 N C ) 2.5 N D ) 4 N

Answer : (B) 3 N

Explanation:

Weight of bird = 2 N
Weight of cage = 1 N

Total weight when bird is sitting: 2+1=3 N

Q5. Which of the following pairs correctly matches a physical concept with its characteristic?
(A) Inelastic Collision: Kinetic energy is conserved.
(B) Conservative Force: Work done in a closed loop is non zero.
(C) Power: Unit is Joule.
(D) Work: Can be negative.

Answer : (D) Work: Can be negative.

Q6.If the linear momentum is increased by 50%, then kinetic energy will increase by
(A ) 50% B ) 100% C ) 125% D ) 25%

Answer: (C) 125%

Q7.One circular ring and one circular disc both having same mass and radius. The ratio of their moment of inertia about the axis passing through their centers and perpendicular to their planes will be
A ) 1 : 1 B ) 2 : 1 C ) 1 : 2 D ) 4 : 1

Answer: B ) 2 : 1

Q8.Energy required to move a satellite of mass m from an orbit of radius 2R to 3R is, (M mass of earth)

Answer:

Q9.The stress strain graph for these materials is shown in the figure. (Assume scale is same for both graph)

(A) Material (ii) is more elastic than material (i) and hence material (ii) is more brittle.
(B)Material (i) & (ii) have the same elasticity and the same brittleness.
(C) Material (ii) is elastic over the larger region of strain as compared to (i)
(D) Material (ii) is more brittle than material (i)

Answer :

Q10.Why does water at the bottom of a lake remain at40⁰𝐶 even when the surface
freezes?
(A) Water has a low specific heat capacity.
(B) Water has maximum density at 40⁰𝐶.
(C) Ice is denser than water.
(D) The ground keeps the bottom warm.

Answer : (B) Water has maximum density at 4°C.

Water shows an unusual property called anomalous expansion.

As water cools down from higher temperatures, it becomes denser.
At 4°C, water reaches its maximum density.
When cooled below 4°C, it becomes less dense and rises to the surface.
The surface water then freezes at 0°C.
Ice (being less dense) floats and forms a layer on top.

Q11.In an isothermal expansion of an ideal gas, what is the relationship between heat supplied (Q) and work done (W) by the gas?
(A)Q= W (B) Q =W (C) Q = ∆ U (D) W ∆U

For an isothermal process (constant temperature) in an ideal gas:

Temperature remains constant.
Internal energy U of an ideal gas depends only on temperature.
Since temperature does not change:

ΔU= 0

Q12.The two ends of a metal rod are maintained at temperatures 100°C and 110°C. The rate of heat flow in the rod is found to be 4.0 J/s. If the ends are now maintained at temperatures 200°C and 210°C, the rate of flow of heat will be
(A ) 16.8 J/s B ) 8.0 J/s C ) 4.0 J/s D ) 44.8 J/s

Answer: C ) 4.0 J/s

Questions number 16 to 18 are Assertion (A) and Reason (R) type questions. Two statements are given one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer from the codes (a), (b), (c) and (d) as given below.
(a) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
(b) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
(c) Assertion (A) is true, but Reason (R) is false.
(d) Assertion (A) is false and Reason (R) is also

13.Answer : (B) Both A and R are true, but R is not the correct explanation of A.

Assertion (A): Minimum number of non-equal vectors in a plane to give zero resultant is three.
True

Two vectors can give zero resultant only if they are equal and opposite.
Since the question says non-equal vectors, minimum required is three (forming a closed triangle).

Reason : If A⃗+B⃗+C⃗=0 then they must lie in one plane. true

14.Answer:(A) Both A and R are true and R is the correct explanation of A.

Assertion (A): Value of radius of gyration of a body depends upon axis of rotation.
True

Changing the axis changes distribution of mass relative to that axis, so radius of gyration changes.

Reason (R): Radius of gyration is the root mean square distance of particles of the body from the axis of rotation.True k²=∑mr²/M
