In Fig the block are at rest a force of `10 N` act on the block of `4 kg` mass .The coefficient of staic friction and the coefficient of kinetic friction are `mu_(s) = 0.2 and mu_(s) = 0.15` for both the surface in contact The magnitudeof frcition force acting between the surface of contact between the `2 kg` and `4 kg` block in this situation is

Options

A. `3 N`
B. `4 N`
C. `3.33 N`
D. Zero

Answer

d

Explanation

The minimum value of F required to be applied on the block to move is `0.2 xx(2 + 4) xx 10 = 12 N` since the applied force is less than the minimum value of force required to move the blocks together the block will remain stationary
