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?

(A) 1N
(B) 2N
(C) 4N
(D) 5N
​

Answer 1

Answer:

I think that the answer is c i.e 4N

Explanation:

hope this helps u

Answer 2

Answer: 4 N

Explanation:

let F be force exerted on 2 kg block by 1 kg block,

Free body diagram:

for 2kg block,

6 - F = 2 * a ---(1)

where a =acc of two blocks

for 1kg block

F - 3 = 1 * a

a = F -3

sub into (1)

6 - F = 2 * ( F -3)

3 F = 12

F = 4 N ---answer

force exerted on 2 kg block by 1 kg block
