Q. For a uniformly charged non-conducting solid sphere, the electric field from its centre

Increases linearly up to the surface

Decreases linearly up to the surface

Remains zero up to the surface

First increases and then decreases up to the surface

$E_{in} = \frac{1}{4 π ϵ _{o}} \frac{q r}{R ^{3}}$
$E_{in} \propto r$

Ein​=4πϵo​1​R3qr​ Ein​∝r

$E_{in} = \frac{1}{4 π ϵ _{o}} \frac{q r}{R ^{3}}$
$E_{in} \propto r$
