In the figure below, a point charge +Q1 is at the center of an imaginary spherical gaussian surface and another point charge + Q2 is outside of the gaussian surface. Point P is on the surface of the sphere. Which one of the following statements is true?
- Both charges + Q1 and + Q2 contribute to the net electric flux through the sphere but only charge + Q1 contributes to the electric field at point P on the sphere.
- Both charges + Q1 and + Q2 contribute to the net electric flux through the sphere but only charge + Q2 contributes to the electric field at point P on the sphere.
- Only the charges + Q1 contributes to the net electric flux through the sphere but both charge + Q1 and + Q2 contribute to the electric field at point P
- Only the charges + Q2 contributes to the net electric flux through the sphere but both charge + Q1 and + Q2 contribute to the electric field at point P.
The correct answer is: Only the charges + Q1 contributes to the net electric flux through the sphere but both charge + Q1 and + Q2 contribute to the electric field at point P

A nonconducting ring of radius R has two charges q and q/2 distributed uniformly on two half of it. A negative charge q/2 (mass = m) is placed at a distance R from the centre of the ring on its axis at a point P and released. If this charge is restricted to move freely only along the axis of the ring, find the speed of this charge when it crosses the centre of the ring
