You measure the electric field strength at points directly above the center of a square plate carrying charge uniformly over its surface. The data are given below. (x is the perpendicular distance above the plate.) Use the data to answer the following questions.

(a) Whatisthetotalchargeontheplate?

(b) Whatisthesizeoftheplate?

(c) There is something missing in these data. What is it?

Step 1

We can find the average of electric field as follows E_{avg}:

Step 2

We can find the average of distance from uniformly charged square plate (x_{avg}) as follows:

Step 3

Given,
