A clock S is based on oscillation of a spring and a clock P is based on pendulum motion. Both clocks run at the same rate on earth. On a planet having the same density as earth but twice the radius
Text Solution
Verified by ExpertsThe correct answer is:
B
. If density is same then 
According to problem 
∴ ∴ 
For clock P (based on pendulum motion) 
Time period decreases on planet so it will run faster because 
For clock S (based on oscillation of spring) 
So it does not change.
