Question

A man is standing on a boat in still water. If he walks towards the shore the boat will:

• A. move away from the shore
• B. remain stationary
• C. move towards the shore
• D. sink

Answer 1

The correct option is A

move away from the shore

1. According to the third law of motion, “ For every action, there is an equal and opposite reaction.”
2. This means, action= - reaction
3. When a man moves towards the shore from a boat, he applies an action on the end of the boat.
4. Due to the action, the boat moves away from the shore.
5. And the boat applies reaction to the man in the opposite direction of the action.
6. This reaction of the boat pushes the man to the shore.

Thus,

Option a) move away from the shore is the correct option.
