Question

Law of length

(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) none of the mentioned

I have been asked this question in semester exam.

This is a very interesting question from Centre of Percussion topic in chapter Simple Harmonic Motion of Machine Kinematics

Answer 1

Correct answer is (c) states the time period (tp) of a simple pendulum is directly proportional to √L , where L is the length of the string.

Explanation: It states the time period (tp) of a simple pendulum is directly proportional to √L , where L is the length of the string.
