Answer 1

A Bob of second pendulum is replaced by another Bob of double mass. The new time period will be

time period of second pendulum is given by, $T=2\pi\sqrt{\frac{l}{g}}$

where, l is length of pendulum, g is acceleration due to gravity.

here it is clear that ,“ time period of second pendulum doesn't depend on mass of bob.

so, if bob is replaced by another bob of double mass. time period remains constant .

e.g., new time period doesn't change and it equals T.
