Question 181 of 311

Which of the following correctly represents the variation of electric potential (V)(V) of a charged spherical conductor of radius (R)(R) with radial distance (r)(r) from the centre?

Show answer and solution

Answer: (C)


As electric field inside the charged conducting sphere is zero, therefore potential will be constant for the inside part.
For outside part, electric potential decreases as V=kqrV=\dfrac{kq}{r} and the conducting sphere behaves like a point charge concentrated at the centre.
