Question

The time period of oscillation of a simple
pendulum varies directly to its length l as l^n
the value of 'n' is
(A) 1
(B)
(D) -
(C) -1​

Answer 1

Explanation:

The time period of simple pendulum can be written as 

T=2πgl

l= length of pendulum 

g= acceleration due to gravity at the position of simple pendulum.

Now when g is unchanged and as 2π is constant, T will only depend on length as the square root of it. So our given statement is true.
