Question

1. Define, describe, or draw a diagram to explain the following terms: (a) lines of force; (b) conservative force; (c) electric potential: (d) dielectric; (e) flux. An electron is located at the origin whose q-_ 1.6 x 10-19 coul and whose mass is 9.11 x 10 kg is in an E-field, E -1000 nt/c, parallel to the x-axis. Calculate: (a) the force, F, on the electron; (b) the acceleration of the electron along the x-axis. Calculate the force between the proton and the electron in the H-Atom. Assume qp 1.6 X 10-19 C, ge1.6 x 10-19C, r 0.53 X 10-10 m. 3. 4. For a square parallel plate capacitor determine the length of one side if C-0.5 farad, d = 1 mm = 1.0 X 10"m Two parallel plates are separated by a distance, d-10 X 10-2 m. There is an E-field of 100 Nt/C between the plates: (a) the voltage between the plates; (b) the work done in moving at charge of 2 uc from 5. one side of the field to the other. 6. A source charge, Qs 20 uc is located at the origin. Calculate (a) the E-field at r = 10 X 10" m away along the x-axis, (b) the voltage at the same distance from the source charge.
