Attached Figure: Two concentric spherical shells with a point charge q at the center. A total charge of Qin=+20 ?C is placed on the inner shell and a total charge of Qout=-25 ?C is placed on the outer shell.

When electrostatic equilibirum is reached, it is found that a charge of Qin,out=+15 ?C forms on the outer section of the inner shell and a charge Qout,out=-10 ?C forms on the outer section of the outer shell. What is the value of q. Then if a charge of q'=-4 ?C and a mass of 0.3kg is released from rest at a distance of r=0.6m directly to the right of the q in the described figure, which is the halfway point between the two shells.

Determine the magnitude of the acceleration of this -4 ?C charge. Assume the weight acts downward.

As the charges given to the shells are redistributed the shells are conducting.

#### Solution Summary

Charge q placed at the center of two concentric spherical conductors is calculated when the charges on the surfaces of conductors are given. The field, force and acceleration of a charged particle is also calculated.
