Question

A parallel plate capacitor is made up of two plates, each a squarer that is 1.0 mm on each side, each having charge of magnitude 1.57 mu C, and separated by a distance of 5.0 mu m. Draw in the electric field between the capacitors. What is the magnitude of the field? If an electron is placed inside the field, what is the magnitude and direction of its acceleration? (Ignore gravity.) The rod shown below has total charge Q uniformly distributed over its length L. It is placed along the x axis, with the left end at the origin (x = 0) Find the electric field at a point P a distance d away from the right end of the rod, In terms of d. L, and the charge density k.

Answer 1

a) The electric field between the plate is shown in figure b) Magnitude is given by 0-CV 8.8510x1x 3x10- = 2.95×10-12F 1.57×10-5 2.95×10-12 -0.532x10 0.532x10 1-0.106 x 1012 y/ml
