Question
A simple pendulum has some time period T. What will be the percentage change in its time period if its amplitude is decreased by 5%?
Options
A.6 %
B.3 %
C.1.5 %
D.0 %
Solution
T = 2√ 
, As it does not depend on amplitude
∴ % change in time period is 0 % Hence option (D) is correct.
, As it does not depend on amplitude∴ % change in time period is 0 % Hence option (D) is correct.
