Question

lectric field lines and equipotential lines for several 2-D dl. (56) (57) #0 E. Questions 1. Based on your calculations, what is the mean value of the electric field between the parallel plates? 022 y 2. What effective charge density (o) would you associate with the (2-D) plates? 3. Equation (57) is derived using the principle of superposition and the formula for the electric field of a single uniformly charged infinite plane (58) 2e Consider two parallel, uniformly charged infinite planes with positive surface charge densities , separated by a distance d. What is the electric field strength between them? 4. What is the electric field strength on either side? 5. A proton is released between two oppositely charged infinite planes with 8.85 10-1" C/m2. By how much does its kinetic energy change if it is accelerated by t electric field over a distance of 10 cm?

Explanation / Answer

Note: Since you have given the electric field between the plates, I am assuming that you want the charge density between the plates.

Answer: 5.33 x 10-10 Cm-2

be the charge density between the plates.

we know,

E = / 0

0 = = 8.854187817×1012 C2 / Nm2

= E X  0

  = 60.22 X  8.854187817×1012

  = 5.33 x 10-10 Cm-2 Answer
