Auniformly charged sphere has a potential on its surface of 450 v. at a radial distance of 7.2 m from this surface, the potential is150 v what is the radius of the sphere?

The radius of the sphere is 3.6 m.

Explanation:

Given that,

Potential of first sphere = 450 V

Radial distance = 7.2 m

If the potential of sphere =150 V

We need to calculate the radius

Using formula for potential

For 450 V

....(I)

For 150 V

....(II)

Divided equation (I) by equation (II)

Hence, The radius of the sphere is 3.6 m.
