Question

A seconds' pendulum is taken on the surface ot moon where acceleration due to gravity is 1/6th of that of Earth. Will the time period of pendulum remain same or increase or decrease. Give a reason

Answer 1

Here is your answer.....
time period will increase  because time period is inversely proportion to the square root of g    so in  moon  g decrease so time period increase

since time period of second pendulum is 2s

so its new time period will be 2x 2.4 = 4.8
