Question
Two forces of 6N and 3N are acting on the two blocks of 2kg and 1kg kept on frictionless floor. What is the force exerted on 2kg block by 1kg block ?
Options
A.1 N
B.2 N
C.4 N
D.5 N
Solution
Both blocks are constrained to move with same acceleration.
6 − N = 2a [Newtons II law for 2 kg block]
N − 3 = 1a [Newtons II law for 1 kg block]
⇒ N = 4 Newton
