A large number of pendulums with identical bobs (mass m) but varying lengths are suspended from a thick thread. Another pendulum of a heavier bob (mass M) is also suspended from the same thred as shown.

This pendulum with the heavier bob is used as a 'driver' to drive the other pendulums called as 'driven' pendulums. Assume that the amplitude of the driver is maintained constant (by some suitable mechanism). Let the frequency of the driver be `f_(0)`
Which of the following will give a straight line graph ?

A

a. log A against t

B

b. log A against 1/t

C

c. A against `t^(2)`

D

d. `A^(2)` against t

Text Solution

Verified by Experts

The correct Answer is:
A
`log A = log A_(0) - kt`

Another pendulum of a heavier bob (mass M) is also suspended from the same thred as shown. This pendulum with the heavier bob is used as a 'driver' to drive the other pendulums called as 'driven' pendulums. Assume that the amplitude of the driver is maintained constant (by some suitable mechanism). Let the frequency of the driver be f_(0) The above pendulum is set into oscillation with an initial amplitude of 10.0 cm. Soon this pendulum comes to rest momentarily and the driver is seen to oscillate with an amplitude of 8.16 cm. Then mass M equals
