A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the center:
1
Increases as r increases from r < R and for r > R
2
Zero as r increases from r < R, decreases as r increases from 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
