Two block of masses 7 kg and 5 kg are placed in contact with each other on a smooth surface. If a force of 6 N is applied on the heavier mass, the force on the lighter mass is

A

3.5N

B

2.5N

C

7 N

D

5N

Text Solution

Verified by Experts

The correct Answer is:
B
`a = (6)/(7+5) = 0.5 m//s^(2)`
Force on lighter mass
`= 5 xx a = 5 xx 0.5 = 2.5 N`
