हिन्दीA hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre:
Correct answer · Option 4
zero as r increases for r < R, decreases as r increases for r > R
Explanation
Inside a hollow metal sphere (\( r < R \)), electric field is zero. Outside (\( r > R \)), \( E \propto \frac{1}{r^2} \), so it decreases as \( r \) increases.
