Question

what is the ratio of potential at the centre to the potential at the surface of a uniformly charged sphere?

Answer 1

Answer:

The ratio is 2. Imagine putting together 8 such cubes to form a larger cube with twice the side length, now the Potential at the center of this new larger cube is 8 times the potential at the corner of each of the smaller cubes if they were isolated.

Answer 2

$\Large{\textsf{\pink{\underline{ANSWER}}}}$

We have to find the electric potential inside a uniformly charged conducting sphere of Radius R and charge Q.

▶We know that electric field inside a conducting sphere is zero, so the potential remains constant at the value it reaches the surface .

$\sf V_inside = \dfrac{1}{4πE_°} \dfrac{Q}{R}$
