1. Analyze Statement I

An electric dipole has charges $+q$ and $-q$, so the net enclosed charge is zero.

By Gauss's law,

Since for a dipole,

we get

So, the net electric flux through the sphere is zero.

Now check the second part: whether electric field is zero anywhere on the sphere.

For a dipole placed at the center, the electric field on the spherical surface is generally not zero everywhere; it varies with angle. In fact, at most points it is nonzero. Hence the intent of the statement is that although total flux is zero, the field itself is not zero on the sphere.

Therefore, Statement I is true.

2. Analyze Statement II

For a charged solid metallic sphere of radius $R$ carrying charge $Q$:

• Inside the conductor, i.e. for $r < R$, $$E = 0$$
• Outside the conductor, i.e. for $r > R$, $$E = \frac{1}{4\pi\varepsilon_0}\frac{Q}{r^2}$$
• On the surface, just outside, $$E = \frac{1}{4\pi\varepsilon_0}\frac{Q}{R^2}$$

So if Statement II claims the electric field at any point depends on $r$ in a way inconsistent with the conductor result (as indicated), then it is false. The standard fact is that inside a metallic sphere electric field is zero, not proportional to $1/r^2$ or any nonzero expression.

Hence, Statement II is false.
