A body executing SHM has amplitude 5 cm and time period 2 s. Maximum velocity is
A. 20π cm/s
B. 5π cm/s
C. 2.5π cm/s
D. 10π cm/s
Answer: Option B
Solution (By JKSSB Mock Tests)
v_max = ωA = (2π/T) A = (2π/2)×5 = 5π cm/s.

Question #2
Two masses, M1 = 3 kg and M2 = 2 kg, are connected by a light inextensible string passing over a frictionless pulley (Atwood machine). The acceleration of the system is (Take g = 10 m/s^2):
A. 5 m/s^2
B. 4 m/s^2
C. 10 m/s^2
D. 2 m/s^2

Correct Answer: Option D


Explanation:
For an Atwood machine, the common acceleration of both masses is given by the formula a = [(M1 - M2) / (M1 + M2)] * g. Substituting the given values: a = [(3 - 2) / (3 + 2)] * 10 = (1 / 5) * 10 = 2 m/s^2. The heavier mass accelerates downwards, the lighter one upwards.

Question #3
In the equation F = ma, if mass is doubled and acceleration is halved, force becomes
A. Four times
B. Same
C. Half
D. Double

Correct Answer: Option B


Explanation:
F = m×a. New force F' = (2m)×(a/2) = m×a = F. So force remains unchanged. This is direct proportionality. Understand the relationship: doubling mass doubles force, halving acceleration halves it, net effect no change.
