Question

a constant force f is applied in horizontal direction as non contact force between M and M is an and between M and M – is an dash them​

Answer 1

According to the data given, Newton's Law of motion be applies to form equation for both the block and then compare to rule out the relation.

Thereby, For the Block M, we have F - N = M a and for the block m, we have N - N' = M a; and for the block M' we have, N' = M' a.

Therefore, we have, N' = M' F / M + m + M' and also N = (m + M) F / M + m + M'. And so, N > N'."

please mark as brilliant please

Answer 2

Answer:



Ans. F=7N

        s = 8 m

        W = F × s

        = 7 N × 8 m

        W = 56J

        ∴ Work done is 56 J.
