Question

The electric field at a distance $\frac{3R}{2}$ from the centre of a charged conducting spherical shell of radius $R$ is $E$. The electric field at a distance $\frac{R}{2}$ from the centre of the sphere is
[NEET- 2010]

• A. $\frac{E}{3}$
• B. Zero
• C. $E$
• D. $\frac{E}{2}$

Answer 1

The correct option is B Zero

We know that electric field inside the shell is zero.
As, the point at distance $\frac{R}{2}$ from the centre lies inside the shell so, the electric field at this point will be zero.

Hence, $\left(A\right)$ is the correct answer.
