13.Oscillations
easy
The time period of a simple pendulum when it is made to oscillate on the surface of moon
A
Increases
B
Decreases
C
Remains unchanged
D
Becomes infinite
Solution
(a) At the surface of moon, $g$ decreases hence time period increases $\left( {{\rm{as}}\,T \propto \frac{1}{{\sqrt g }}} \right)$
