Question

if acceleration of A is 2 m/s2
which is mar
g
ofthen the value of inctional force applied by
on Ais
10 kg
)
(1)50 N
(2) 20 N
14) None of these
(9)10 N​

Answer 1

Answer:

20N check this answer is right I think it is right

Answer 2

Answer:

C. 10 N

Explanation:

If we consider observer on A then B tends to slide down backward with same acceleration I.e. 2 m/s^2.So frictional force will make the B to be at rest.

FBD of B :

5×2=10N <____._____> FRICTIONAL FORCE

As the B is in equilibrium so Frictional force = 10 N
