Q2.A particle executing SHM crosses points A and B with the same velocity. Having taken 3 s in passing from A to B, it returns to B after another 3 s. The time period is

Answer : Option C Explaination / Solution: No Explaination.

Q3.The length of a second’s pendulum on the surface of the Earth is 0.9 m. The length of the same pendulum on surface of planet X such that the acceleration of the planet X is n times greater than the Earth is

Answer : Option A Explaination / Solution: No Explaination.

Q5.Two
bodies A and B whose masses are in the ratio 1:2 are suspended from two
separate massless springs of force constants k_{A} and k_{B}
respectively. If the two bodies oscillate vertically such that their maximum
velocities are in the ratio 1:2, the ratio of the amplitude A to that of B is

Answer : Option B Explaination / Solution: No Explaination.

Q6.A spring is connected to a mass m suspended from it and its time period for vertical oscillation is T. The spring is now cut into two equal halves and the same mass is suspended from one of the halves. The period of vertical oscillation is

Answer : Option B Explaination / Solution: No Explaination.

Q7.The
time period for small vertical oscillations of block of mass m when the masses
of the pulleys are negligible and spring constant k_{1} and k_{2}
is

Answer : Option A Explaination / Solution: No Explaination.

Q8.A
simple pendulum has a time period T_{1}.
When its point of suspension ismoved
vertically upwards according as y = k t^{2}, where y is vertical distance covered and k = 1 ms^{−2}, its time period becomes T_{2}. Then T_{1}^{2}/T_{2}^{2}
is (g=10ms^{-2})

Answer : Option C Explaination / Solution: No Explaination.

Q9.An
ideal spring of spring constant k, is
suspended from the ceiling of a room and a block of mass M is fastened to its lower end. If the block is released when the
spring is un-stretched, then the maximum extension in the spring is

Answer : Option C Explaination / Solution: No Explaination.

Q10.A
pendulum is hung in a very high building oscillates to and fro motion freely
like a simple harmonic oscillator. If the acceleration of the bob is 16 ms^{−2} at a distance of 4 m
from the mean position, then the time period is

Answer : Option D Explaination / Solution: No Explaination.
