1. A hollow metal sphere of radius R is uniformly charged. The electricfield due to the sphere at a distance r from the centre
(1). decreases as r increases for r < R and for r > R
(2). increases as r increases for r < R and for r > R
(3). zero as r increases for r < R, decreases as r increases for r > R
(4). zero as r increases for r < R, increases as r increases for r > R
