Question

A hollow metal sphere of radius $R$ is uniformly charged. The electric field due to the sphere at a distance $r$ from the centre

• A. increases as $r$ increases for $r<R$ and for $r>R$
• B. zero as $r$ increases for $r<R$, decreases as $r$ increases for $r>R$
• C. zero as $r$ increases for $r<R$, increases as $r$ increases for $r>R$
• D. decreases as $r$ increases for both$r<R$ and $r>R$

Answer 1

The correct option is B zero as $r$ increases for $r<R$, decreases as $r$ increases for $r>R$


$E=0$ for $r<R$
$E$ decreases with $r$ for $r>R$
