In a cricket match, the fielder draws his hands backward after receiving the ball in order to take a catch because:

1. His hands will be saved from getting hurt.

2. He deceives the player.

3. It is a fashion.

4. He catches the ball firmly.

A ball is traveling with uniform translatory motion. This means that:

1. it is at rest.
2. the path can be a straight line or circular and the ball travels with uniform speed.
3. all parts of the ball have the same velocity (magnitude and direction) and the velocity is constant.
4. the center of the ball moves with constant velocity and the ball spins about its center uniformly.

A meter scale is moving with uniform velocity. This implies:

1. the force acting on the scale is zero, but a torque about the centre of mass can act on the scale.
2. the force acting on the scale is zero and the torque acting about the centre of mass of the scale is also zero.
3. the total force acting on it need not zero but the torque on it is zero.
4. neither the force nor the torque needs to be zero.
