A charge of 3.14 × 10−6 C is distributed uniformly over a circular ring of radius 20.0 cm. The ring rotates about its axis with an angular velocity of 60.0 rad s−1. Find the ratio of the electric field to the magnetic field at a point on the axis at a distance of 5.00 cm from the centre.

Explanation:
Step 1:
Given data in the question
Charges of Magnitude,
Radius of the circle ,
Angular velocity of the circle,
Time to Transition
Step 2:
The small element 1 and 2 of the ring respectively, E1 and E2 denote the electric area at a point on the axis at a distance of 5.00 cm from the centre.
E is the resulting electric area at a stage on the axis, at a distance of 5.00 cm from the center due to the whole ring.
Step 3:
The electric area at a stage on the axis is x distant from the centre
Step 4:
The magnetic field is given at a stage on the axis x distant from the centre
