When moving down the hill friction force exerted by the hill to shoe of man will be in the direction
مر
Option 1:
Towards upside the hill
Option 2:
Towards downside the hill
Option 3:
Normal to the shoe surface
Option 4:
None of the above​

Answer 1

Answer:

in my opinion the correct answer is a

Explanation:

As The direction of friction is always opposite that of motion

hope it will help you

Answer 2

Answer:

The correct option is: Option 2: Towards downside the hill

Explanation:

• Reason: Here the man is moving downward so the force of friction will be exerted downward as we know friction helps us to move forward.
• Detail explanation: When the man exerted a force to the hill, the hill also exerted a reaction force on the shoe of the man because of Newton's 3rd law.

         Reaction force(exerted by hill) has two components -

(i) perpendicular component, which is normal reaction.

(ii) horizontal component, which is the frictional force. The direction of this force is in the direction of motion, so it helps to move forward (downward from hill).
