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<Rr < R and for r>Rr > R

2

Zero as r increases for r<Rr < R, decreases as r increases for r>Rr > R

3

Zero as r increases for r<Rr < R, increases as r increases for r>Rr > R

4

Decreases as r increases for r<Rr < R and for r>Rr > R

Step-by-Step Solution

For a hollow charged sphere, the electric field inside (r<Rr < R) is zero. Outside (r>Rr > R), the field is E=kqr2E = \frac{kq}{r^2}, which decreases as rr increases.
