A 0.10 kg mass is oscillating on Planet X at a small angle from a light string of length 0.20 m with a period of 0.63 s.
What is the acceleration of gravity on Planet X?

the acceleration of gravity on Planet X is 19.89 m/s^2

Explanation:

The computation of the acceleration of gravity on Planet X is shown below:

T = 2π√l ÷ √g

g = l ÷ (T÷ 2π)^2

= 4π^2l ÷ T^2

= 4π^2× 0.2 ÷ 0.63^2

= 19.89 m/s^2

Hence, the acceleration of gravity on Planet X is 19.89 m/s^2

In this way it should be calculated
