Question 1

Medium

An isolated spherical conductor is charged. The conductor has a radius $R$ and an electric potential $V$ at its surface. The electric field strength at its surface is $E$ .

A diagram showing a charged spherical conductor of radius R. A horizontal dashed line starts from the center of the sphere, goes to the right, exits the sphere's surface, and terminates at a point P. The distance from the surface of the sphere to point P is labeled 3R.

Point $P$ is at a distance of $3 R$ from the surface of the conductor.

What are the electric field strength and electric potential at $P$ ?

Electric field strength: $E4\frac{E}{4}$ , Electric potential: $V16\frac{V}{16}$

Electric field strength: $E16\frac{E}{16}$ , Electric potential: $V4\frac{V}{4}$

Electric field strength: $E9\frac{E}{9}$ , Electric potential: $V3\frac{V}{3}$

Electric field strength: $E16\frac{E}{16}$ , Electric potential: $V16\frac{V}{16}$
