Solution:
Spring force acting on 1 kg block is F = m.a = 1 N
Same spring force will act on 2 kg block in opposite direction. Thus net force acting on 2 kg block is 5N - 1 N = 4N
Acceleration of the block will be 4 N/2 kg = 2 m/s²
Two blocks of masses 1 kg and 2 kg are connected with massless spring as shown. If the acceleration of 1 kg block is 1 m/s² towards right then the acceleration of 2 kg block is:
