Question

Two simple pendulums A and B have equal length but their bobs weight 50 gf and 100 gf respectively. What would be the ratio of their time periods? What is the reason for your answer?​

Answer 1

Answer:

2π√(L/g) is the Time Period of pendulum. So, Time Period doesn't depend on mass of the bob. So, both pendulum will have same Time Period if length of string attached to it is same. Hence, 1 : 1 would be the answer

Answer 2

Answer:

Ration of time period is 1

Explanation:

Time period of simple pendulum is

$t \: = 2\pi \: \sqrt{ \frac{l}{g} }$

Here u can see that Time person doesn't depend on weight of bob so their time period ratio is 1
