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

(1) Increases as r increases for r < R and for r > R

(2) Zero as r increases for r < R, decreases as r increases for r > R

(3) Zero as r increases for r < R, increases as r increases for r > R

(4) Decreases as r increases for r < R and for r > R

(1) Increases as r increases for r < R and for r > R

(2) Zero as r increases for r < R, decreases as r increases for r > R

(3) Zero as r increases for r < R, increases as r increases for r > R

(4) Decreases as r increases for r < R and for r > R
