35. A spherical conductor has a radius of 14.0 cm and a charge of 26.0 mC. Calculate the electric field and the electric poten- tial at (a) r 5 10.0 cm, (b) r 5 20.0 cm, and (c) r 5 14.0 cm from the center.

Therefore,

Explanation:

Given:

A spherical conductor has a radius of 14.0 cm

Q = 26.0 μC ( Assume it to be microC in the question it is miliC )

To Find:

Electric potential at

(a) r 5 10.0 cm, (b) r 5 20.0 cm, and (c) r 5 14.0 cm from the center.

Solution:

Electric potential due to point charge Q at any distance r from the charge is,

Where,

V = Electric Potential

k = Coulombs constant = 9 × 10⁹ Nm²/C².

Q = Charge

r = distance in meter

Substituting the values we get

At r = 10 cm = 0.1 m

At r = 20 cm = 0.2 m

At r = 14 cm = 0.14 m

Therefore,

a.) is the correct answer.
