Question

what happens to the coefficient of friction when the normal reaction is Halved​

Answer 1

Answer:

If the normal is doubled there will be no change in coefficient of friction, as it only depends upon the nature of pair of surface in contact. So doubling the normal will just double the frictional force and will not affect the coefficient of friction.
