An electron is constrained to the central perpendicular axis of a ring of charge of radius 2.2m and charge 0.021 mC. Suppose the electron is released from rest a distance 0.098m from the ring center. It then oscillates through the ring center. Calculate its period in seconds. (The electron is always much closer to the ring center than a radius.)

A total charge Q=8 x 10-8 C is distributed uniformly on the sheet. A pith ball (a small non-conducting ball made of a light spongy plant material called "pith"), also with charge Q = 8 x 10-8 C, is fixed 50 cm directly above the center of the plate. Point A is located 5 cm from the plate, directly below the pith ball, as shown. ++ Pith ball 0.050 m XA 0.50 m a) What is the electric field at A due to the plate (magnitude and direction)? b) What is the electric field at A due to the pith ball (magnitude and direction)? c) What is the net electric field at A (magnitude and direction)? d) What force (magnitude and direction) would an electron experience if it were located at point A?arrow_forward
- 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 parallel plates, each charged equally and oppositely to the other, are separated by 2.3500 cm. A proton is let go from rest at the positive plate's surface and, at the same time, an electron is let go from rest at the negative plate's surface. What is the distance between the negative plate and the point where the proton and the electron go by each other?
