Problem

A simple pendulum has time period

T_1

. The point of suspension is now moved upward according to the relation

y = Kr^2

, (

K = 1 \text{ m/s}^2

) where

y

is the vertical displacement. The time period now becomes

T_2

. The ratio of

\frac{T_1^2}{T_2^2}

is (g =

10 \text{ m/s}^2

) a. 5/6 b. 6/5 c. 1 d. 4/5
