There is a uniform electrostatic field in a region. The potential at various points on a small sphere centred at P, in the region, is found to vary between the limits 589.0V to 589.8V. What is the potential at a point on the sphere whose radius vector makes an angle of 600 with the direction of the field ?

Potential gradient is equal to
"v=589.8 V \u2013 589.0 V = 0.8 V (1)"
Potential gradient is given by formula:
"v=Ed \\cos 60\u00b0 (2)"
Using (1) and (2) we got:
"v=0.8 V\u00d70.5 =0.4 V (3)"
The potential at a point on the sphere is equal to
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
