E=( KQr / R 3) r < R E =( KQ / r 2) r > R

Q. For a uniformly charged sphere, the electric field from its centre :-

increases linearly upto the surface

decreases linearly upto the surface

remains zero upto the surface

first increases and then decreases upto the surface

$E = \frac{K Q r}{R ^{3}} r < R$
$E = \frac{K Q}{r ^{2}} r > R$

Q. For a uniformly charged sphere, the electric field from its centre :-

increases linearly upto the surface

decreases linearly upto the surface

remains zero upto the surface

first increases and then decreases upto the surface

E=R3KQr​r<R E=r2KQ​r>R

$E = \frac{K Q r}{R ^{3}} r < R$
$E = \frac{K Q}{r ^{2}} r > R$
