(a) A simple pendulum is made by suspending a bob of mass 500 g by a string of length 1 m . Calculate its time period at a place where g = 10 `m s^(-2)` .
(b) How will the time period in part (a) the affected if bob of mass 100 g is used, keeping the length of string unchanged ?

Text Solution

Verified by Experts

(a) Given : l=1 m , g = `10 ms^(-2)`
Time period `T = 2pi sqrt(l/g) = 2 xx 3.14 xx sqrt(1/(10))`
`=1.99 ` s
(b) On changing the bob by another bob of different mass, the time period will remain unaffected because it does not depend on the mass of bob.
