Electric Field: Practice Problem & Solution

A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre (2019)
Increases as r increases for $r R$
Zero as r increases for $r R$
Zero as r increases for $r R$
Decreases as r increases for $r R$

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:

Inside a hollow metal sphere, the electric field is zero ($E = 0$ for $r R$.
