Question

(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.

Answer 1

Answer:

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.
