Question

A body is revolving with a constant speed along a circular path. If the direction of its velocity is reversed,
keeping speed unchanged, then

Options:

a) the centripetal force does not suffer any change in both magnitude and direction
b) the centripetal force does not suffer any change in magnitude but its direction is reversed
c) the centripetal force disappears
d) centripetal force will be doubled​

Answer 1

Answer:

d) centripetal force will be doubled

Explanation:

A body is revolving with a constant speed along a circular path. If the direction of its velocity is reversed keeping speed unchanged then. 1) The centripetal force does not suffer any change in both magnitude and direction. ... 4) Centripetal force will be double.
