Question

Two blocks of mass 10 kg and 40 kg are connected by a string. The 40 kg block is pulled by a
constant force of 60 N. Find the frictional force acting on 10 kg block? (g = 10 m/s2)
For the 10 kg block the u=0.3
For the 40 kg block the u=0.2 and the frictional force is 60 N on the same 40 kg block
options
(A) 10 N
(B) 20 N
(C) Zero
(D) 30 N​

Answer 1

Answer:

Explanation:

FRICTIONAL FORCE = COEFFICIENT OF FRICTION * NORMAL FORCE

=0.3*100

=30N
