Charge is distributed on the surface of a spherical conducting shell. A point particle with charge q is inside. If polarization effects are negligible the electrical force on the particle is greatest whenA. it is near the inside surface of the balloonB. it is at the center of the balloon C. it is halfway between the balloon center and the inside surface D. it is anywhere inside (the force is same everywhere and is not zero) E. it is anywhere inside (the force is zero everywhere)"

A. it is near the inside surface of the balloon

Explanation:

As we can see in the question shown above, the electric charge is distributed on the surface of a spherical conductive envelope, a balloon. This means that the surface of the balloon becomes automatically energized and the regions closest to that surface experience greater electrical force. With this we can affirm that the center of the balloon has a lesser electrical force, since it is the region farthest from the surface.

Based on this, we can say that the particle that is inside the balloon will be subjected to a greater electrical force when it is close to the inner surface of the balloon.

real, smaller and upside-down.   so the answer should be b.
