Question

Solve the following question

Answer 1

Answer is option A i.e. in the first case.

In the first case we can see that two men are applying the force from one direction so it helps the object to move.

For example two men are applying the force of 10N each on the box

10N + 10N = 20N

But in the second case there are two men who are applying the force in the opposite direction on the object so the a is not moving.

Example : Two men are applying 15N force from each side but they are opposite to each other.

So,

15N - 15N = 0N

Hence 20N > 0N

So option A is correct

Answer 2

case a
