to go from one extreme position to the mean position. What is the time period of the
pendulum?

Answer 1

Answer:

The bob takes 0.5 sec to move from mean position to an extreme end which is equal to

4

1

th of its time period.

so,T=2 s

Again if l is the length of bob

T=2π

g

l

⇒l=

4π

g

=

4×π
