(Choose the x-axis to point along the axis of the ring.) 1.00 cm _________ î MN/C 5.00 cm _________ î MN/C 30.00 cm _________ î MN/C 100.00 cm _________ î MN/C

Charges q1 and q2 are located on the corners of a rectangle. If width w=60 cm and length l=80.2 cm find the magnitude of the electric field (in N/C) at P when q1= 4.08 nC and q2=1.43 nC.

(10%) Problem 4: A solid aluminum sphere of radius r! 0.038 m is charged with qi = +42 μC of electric charge. It is surrounded concentrically by a spherical copper shell of inner radius r2-0.065 m and outer radius r,-0.078 m. An electric charge of q,--9 5 μC is placed on the copper shell.
