(a) Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on Earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. You send the clock to a location on the Moon where the magnitude of the acceleration due to gravity is 1.65 m/s2. Does the clock run fast or slow on the Moon?
(b) If the clock is started at 12:00 noon, what will it read after a time of 20.6 h has elapsed on Earth? Enter the time to the nearest minute.
We know that time period of simple pendulum depends upon only two things 1) Length of string of pendulum 2) Acceleration due gravity
It is given by relationship T = 2π √ L/g
Since, length is fixed, but acceleration due to gravity is different , So Time period will be more on moon. So clock will be slow.
