Questions
In the following examples, which represents periodic but not simple harmonic motion
a) Rotation of earth about its own axis
b) Revolution of moon around the earth
c) Swinging pendulum from a fixed axis
d) Marble released from top of a smooth hemispherical bowl
detailed solution
Correct option is A
Any to and from motion which is also periodic is said to execute simple harmonic motion.Statement: (a):- It is periodic but does not have a to and pro motion. Hence the right statement.Statement: (b):- It is periodic but does not have to and pro motion about a fixed point. Hence the right statement.Statement: (c):- It is periodic and also has to and pro motion about a fixed point making it a simple harmonic motion. Hence a wrong statementStatement: (d):- It is periodic and also has to and pro motion about a fixed point making it a simple harmonic motion. Hence a wrong statement.This makes option (1) the right answerSimilar Questions
