Question

Problem 22.58
Three large but thin charged sheets are parallel to each other as shown in the figure

. Sheet I has a total surface charge density of 6.6nC/m2 , sheet II a charge of -1.9nC/m2 , and sheet III a charge of 5.0nC/m2 .

Part A
Estimate the magnitude of the force per unit area on sheet I, in N/m2?
Express your answer using two significant figures.
∣∣FA∣∣I =

Part C
Estimate the magnitude of the force per unit area on sheet II, in N/m2?
Express your answer using two significant figures.
∣∣FA∣∣II =


Correct
Part E
Estimate the magnitude of the force per unit area on sheet III, i

Answer 1

Tricky to answer this without knowing how the sheets are arranged, do you know the order and separation between the sheets ?
