Answer 1

Answer:

) Gravitational force

Explanation:

Answer 2

Answer:

Frictional force acts between pulley and rope.

Explanation:

As the pulley and rope are in contact, friction is generated between the two bodies.

Friction is a force which acts when two bodies come in contact with each other. It opposes relative slipping between the bodies in contact.

Frictional force is of two types : Static and Kinetic.

Static friction acts when there is tendency of slip between the bodies but there is no actual slipping and friction is able to keep the bodies together.

Kinetic Friction acts when the two bodies start slipping relative to each other.

The maximum value of frictional force is called limiting friction.
