So option (E) will be correct answer
Explanation:
We have given length of the pendulum l = 2 m
Time period of the pendulum T = 2 sec
We have to find acceleration due to gravity g
We know that time period of pendulum is given by
Squaring both side
So acceleration due to gravity is 20
So option (E) will be correct answer.
