Watch the green man. Which force(s) are acting in this situation?

• Frictional Force only.

• Gravitational Force only.

• Muscular Force only.

• Muscular and Gravitational Force.

Observe the image carefully. What's NOT happening here?

• People on the left side win the game.

• Nobody wins.

• This is balanced situation.

• Resultant Force is zero.

Let's say that the box in the picture will move. And it will move in the right direction. This is happening because-

• Both the men are pushing it towards right.

• Both the push and pull are in the opposite direction.

• Both the push and pull are in the same direction.

In Fig 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?

• Magnitude of force applied by A is greater than that of B

• Magnitude of force applied by A is smaller than that of B.

• Net force on the block is towards A.

• Magnitude of force applied by A is equal to that of B.
