Question

A second's pendulum is taken to a planet where the acceleration due to gravity is 16 times that on earth will stop what would be the time period of the pendulum on the planet? *
​

Answer 1

Explanation:

Time period will be doubled

Time period with acceleration due to gravity g

T

1

=2π

g

l

for a second's pendulum time period is 2s

when acceleration is one -fourth

T

2

=2π

4

g

l

=2×2π

g

l

=2×T

1

=4×2=4s
