Question

if the accelaration due to gravity is decreased 8 times, then what will be the new time period?

Answer 1

Answer:

....

Explanation:

Assuming that the time period you refer to here is of SHM of a simple pendulum,

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

So the value of g will become g/8.

So as per formula time period will become 2√2 times.
