The figure below shows two nonconducting spherical shells fixed in place. Shell 1 has uniform surface charge density +6.0 μC/m² on its outer surface and radius 3.0 cm. Shell 2 has uniform surface charge density -4.4 μC/m² on its outer surface and radius 2.0 cm. The shell centers are separated by L = 13 cm. What are the magnitude and direction of the net electric field at x = 2.0 cm? magnitude N/C direction -Select- Shell Shell Oo

Two conducting hollow spheres share a common center. The inner sphere has the radius a = 5.0 cm and charge +3.2x10-6 C. The outer sphere has the radius b = 32 cm and charge -4.0x10-6 C. What is the electric field (in N/C) at a point P, r = 20 cm from the center of the spheres?

The figure shows a very large nonconducting sheet that has a uniform surface charge density o = -2.70 µC/m2; it also shows a particle of charge Q = 7.40 µC, at distance d from the sheet. Both are fixed in place. If d = 23.0 cm, at what (a) positive and (b) negative coordinate on the x axis (other than infinity) is the net electric field of the sheet and particle zero? (c) If d = 70.0 cm, at what coordinate is É net = 0? (a) Number Units (b) Number i Units (c) Number i Units >
