Law of gravity
(a) states the time period (tp ) of a simple pendulum does not depend upon the mass of the body suspended at the free end of the string.
(b) states the time period (tp ) of a simple pendulum does not depend upon its amplitude of vibration and remains the same, provided the angular amplitude (θ) does not exceed 4°.
(c) states the time period (tp) of a simple pendulum is directly proportional to √L , where L is the length of the string.
(d) states the time period (tp ) of a simple pendulum is inversely proportional to √g , where g is the acceleration due to gravity.
I had been asked this question during a job interview.
