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 589.0 V to 589.8 V. What is the potential at a point on the sphere whose radius vector makes an angle of 600 with the direction of the field ?
As we learnt in
Relation between field and potential -
Potential gradient is given by
Hence maximum potential at a point on the sphere =589.4 V
