What is the potential energy on q due to this uniformly charged circular ring of radius r? (Point q is at the centre of the circle)

Question

Samyak Jain · Answer

Potential at the centre due to circular ring of radius r and having uniform charge Q is KQ / r . Point charge q is located at the centre of the ring. Thus, potential energy of the system = charge q x potential = q x KQ / r = KQq / r .

Khimraj · Answer

Steps and Understanding :
1) We will find Electric Potential by writing V = K(q) / d
where q is charge contained in ring.
d - distance of charge from point .
k = 1/4π£°
where £° is permitivity in vacuum.

2) We will find Electric Field by
E = -dV/dx
