An infinite line of positive charge lies along the y axis, with charge density λ = 2.00 μC/m. A dipole is placed with its center along the x axis at x = 25.0 cm. The dipole consists of two charges ±10.0 μC separated by 2.00 cm. The axis of the dipole makes an angle of 35.0° with the x axis, and the positive charge is farther from the line of charge than the negative charge. Find the net force exerted on the dipole.

A solid non-conducting sphere of radius 3 cm has a charge of +24 micro(u)C. A conducting spherical shell of inner radius 6 cm and outer radius 10 cm is concentric with the solid non-conducting sphere and carries a charge of -10 micro C. What is the force on an electron located midway in the space between the shell and the solid sphere?

A solid core carrying excess charge, Q = 47.6 μC, is located at the center of concentric spherical shells. The two spheres are joined by a hollow plastic tube that starts at the radius of the small sphere, r = 13.5 cm, and ends at the radius of the large one, R = 29.7 cm. When a charge, q = 7.8 μC, is placed at the inner end of the tube and released from rest, it accelerates straight through the tube and out the other end as shown. AUE= (a) How much did the electric potential energy change as the particle moved from one end of the tube to the other? Write your answer symbolically, in terms of Q, q, r, R and constants (as needed), then calculate its numeric value. kao ( + - 1/2 ) R = 13.5 J R x J (b) How much electric potential energy will be left when the little charge is 56.7 cm from the core?

Two point charges are fixed on the y axis: a negative point charge q1 = - 28 μC at y1 = + 0.15 m and a positive point charge q2 at y2 = + 0.35 m. A third point charge q = + 9.2 μC is fixed at the origin. The net electrostatic force exerted on the charge q by the other two charges has a magnitude of 23 N and points in the +y direction. Determine the magnitude of q2.
