HEN N mg Ukmg N none of the above mg MEN N

Answers

The last part (figure shown below) is the answer.

As the gravitational force mg will always act vertically downward.

Friction force is equals to friction coefficient multiplied by the normal reaction at that surface and in the direction opposing the motion of the body.

mg ni N N
