Q1:

To double the period of oscillation of a simple pendulum

A the mass of its bob should be doubled

B the mass of its bob should be quadrupled

C its lenght should be quadrupled

D its length should be doubled.

ANS:C - its lenght should be quadrupled

Length of pendulum should be double or twice for the single oscillation so if we want to double oscillation then the length should be four times.
