MCQ

The period of a simple pendulum is doubled, when

A
Its length is doubled
B
The mass of the bob is doubled
✓
Its length is made four times
D
The mass of the bob and the length of the pendulum are doubled

✓

Answer

Correct option: C.

Its length is made four times

c
(c) $T = 2\pi \sqrt {\frac{l}{g}} $

==> $T \propto \sqrt l $
