Electric Field: Practice Problem & Solution

A hollow sphere of radius $1 \text{ m}$ is given a positive charge of $10 \mu \text{C}$. The electric field at the centre of hollow sphere will be: (1990)
$60 \times 10^3 \text{ Vm}^{-1}$
$90 \times 10^3 \text{ Vm}^{-1}$
Zero
Infinite

Solution Explained:

To solve this problem, we apply the core principles of Electric Field. Understanding the underlying formula is key to arriving at the correct answer below:

The electric field at any point inside a charged hollow conducting sphere is always zero, regardless of the amount of charge on its surface. Therefore, the electric field at the center is zero.
