Question

70. Two blocks A and B of masses 10 kg and 15 kg
are placed in contact with each other rest on a
rough horizontal surface as shown in the figure.
The coefficient of friction between the blocks and
surface is 0.2. A horizontal force of 200 N is applied
to block A. The acceleration of the system is
(Take g = 10 m s-)
a)4 m s-2

(b) 6 m s-2
(c) 8 m s-2
(d) 10 m s-2
A
B​

Answer 1

Explanation:

Hope it helped

U just need to apply

F=m*a

Here m =m1+m2
