Question 1
In the figure, two boys A and B are shown applying force on a block. If the block moves towards the right, which one of the following statements is correct?

(a) Magnitude of force applied by A is greater than that of B.
(b) Magnitude of force applied by A is smaller than that of B.
(c) Net force on the block is towards A.
(d) Magnitude of force applied by A is equal to that of B.

Solution

(a) The magnitude of the force applied by A is greater than that of B.

Since the block moves towards B, the force applied by A will be more.
