Question

A spherical conductor of radius $10\text{cm}$ has a charge of $3.2\mu \text{C}$ distributed uniformly over it. The magnitude of electric field at a point $5\text{cm}$ from the centre of sphere is

• A. $1.28\times {10}^5{\text{NC}}^{-1}$
• B. $2.88\times {10}^6{\text{NC}}^{-1}$
• C. $1.15\times {10}^7{\text{NC}}^{-1}$
• D. Zero

Answer 1

The correct option is D Zero

Inside charged spherical conductor electric field is zero.
