Answer 1

Answer:

A block of mass m slides down a smooth vertical circular track. During the motion, the block is in

(a) vertical equilibrium

(b) horizontal equilibrium✔..............................................

(c) radial equilibrium

(d) none of these.

Answer 2

A block of mass m slides down a smooth vertical circular track. During the motion, the block is in (c) Radial equilibrium.

Explanation:

For a body that slips on a vertical circle, the vertical circle can be left and therefore there is a force acting on it to hold it in the vertical circle.

A pull to the center of the circle is applied by force.    

This force is known as force radial.      

The radial force the moves the body in such a way that it keeps moving on the circular path is what keeps the object in radial equilibrium.

Consequently the body is in radial equilibrium.

Therefore, Option(c) is the correct answer.
