Answer 2

Answer:

your answer

Explanation:

Let the force applied by string to the block be T. For part (a), consider one system is block and other string. Let the acceleration of the system (block + string) be a.

Now we apply Newton's law to each of them.

For system II : F−T=ma......(i)

For system I : T=Ma......(ii)

AFter solving (i) and (ii), a=  

M+m

F
