Question

find the charges in the length of a second`s pendulum if the acceleration due to gravity at place change from 9.75 m/s^2 to 9.8 m/s^2​

Answer 1

Answer:

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
