Let `F,F_N and f` denote the magnitudes of the contact force, normal force and the friction exerted by one surface on the other kept in contact. If none of these is zero,

A

`F gt N`

B

`F gt f`

C

`N gt f`

D

`(N - f) lt F lt (N + f)`

Text Solution

Verified by Experts

The correct Answer is:
C
The coefficient of friction may be greater than one. Hence `N gt f(= mu mg)` is wrong`.
