Question

The value of contact force between masses 3 kg
and 4 kg is
45 N-2kg 3kg
4kg IN
(2) 30 N
(1) 20 N
(3 250
(4) 15N​

Answer 1

Answer: , and .

Explanation:

Given that,

Mass of block 1 = 1 kg

Mass of block 2 = 2 kg

Mass of block 3 = 3 kg

Force = 12 N

(I). The acceleration of the system of these three blocks is

(II). The contact force acting on 2 kg block by first block of 1 kg is

(III). The contact force on 3kg block is

Hence, this is the required solution.
