Q.

In the arrangement shown in figure, coefficient of friction between the two blocks is 0.5. The force of friction acting between the two blocks is

View Answer

Correct choice: A

Explanation:

Let the acceleration of both the blocks towards left is ‘a’, then

The maximum friction between the two blocks can be.
f = 8N
Friction between the two blocks is 8N
fmax μ mg
fmax = (0.5) 2(10) = 10N
