Question

10.To and fro motion of an object about its mean position is:
a) Linear motion b) Oscillatory motion
c) Rectilinear motion d) None of these

Answer 1

Answer:

To and fro motion of an object about its mean position is oscillatory motion

Answer 2

b) Oscillatory motion

In an oscillatory motion,the particle vibrates back and forth about its mean position , therefore we can say that the to and fro motion is the oscillatory motion
