period=60sec/12=5sec
period=2PIsqrt(length/g) solve for length.
period=2PIsqrt(length/g) solve for length.

12oscillations per minute can also be written as:
12/60 oscillation per second
So we get 1oscillation per second
Now ,we know the formula
T=2π√l/g
Put the values in in rhe formula
T=5sec
g=10m/sec
So,
5=2π√l/g
Now squaring both side we get
25=2×2×π×π×l/10
Put value of π as 22/7
Then value of l =6.3m
