Question

Intially a particle is at rest at the highest point of a circle of radius r. When particle is displaced

slowly then calculate the depth at which it will leave the vertical circle just below the highest poin​

Answer 1

Explanation:

When all the forces that act upon an object are balanced, then the object is said to be in a state of equilibrium. The forces are considered to be balanced if the rightward forces are balanced by the leftward forces and the upward forces are balanced by the downward forces. This however does not necessarily mean that all the forces are equal to each other. Consider the two objects pictured in the force diagram shown below. Note that the two objects are at equilibrium because the forces that act upon them are balanced; however, the individual forces are not equal to each other. The 50 N force is not equal to the 30 N force.
