Time period of second pendulum is given by-xA0-xA0- T-2-x3C0-x221A-lg-x27F9-xA0-T-x221D-x221A-lThus if the length if second pendulum is increased by 4 times- its time period gets increased by 2 times-

If length of second pendulum becomes four times, then its time period will become :four timeseight timestwo timessame as before

Time period of second pendulum is given by T=2π√lg⟹ T∝√lThus if the length if second pendulum is increased by 4 times, its time period gets increased by 2 times.

If length of second pendulum becomes four times, then its time period will become :
four times
eight times
two times
same as before

Time period of second pendulum is given by $T = 2 π \sqrt{\frac{l}{g}}$
$⟹ T \propto \sqrt{l}$
Thus if the length if second pendulum is increased by 4 times, its time period gets increased by 2 times.
