Question

A spherical cavity of radius 6.50 cm is at the center of a metal sphere of radius 17.5 cm . A point charge 4.90 μC rests at the very center of the cavity, whereas the metal conductor carries no net charge.

a.Determine the electric field at a point 5.00 cm from the center of the cavity.

b.Determine the electric field at a point 8.00 cm from the center of the cavity.

c.Determine the electric field at a point 50.0 cm from the center.
