Question

Electric fiels due to a charged ring on its axis at a distance x of radius r is.

Answer 1

Answer:

Explanation:

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

3) In diagram in pic, x is distance from centre of ring to that point.

For Calculation see pic.
