Which figure shows the correct electric field?
Which of the following electric field patterns is the wrong electric field pattern?
What force does the electric field of \(7.19 \times 10^5 \space \text N \text C^{-1}\) exert on a point charge of \(0.250 \space \mu \text C\)?
(A) \(0.200 \space \text N\)
(B) \(0.190 \space \text N\)
(C) \(0.180 \space \text N\)
(D) \(0.170 \space \text N\)
What is the magnitude and direction of an electric field that exerts a \(2.00 \times 10^5 \space \text N\) upward force on a \(1.75 \space \mu \text C\) charge?
Dry air will support a maximum electric field strength of about \(3.0 \times 10^6 \space \text {V/m}\). Within that value, the field creates enough ionization in the air to make the air a conductor. This allows a discharge or spark that reduces the field.
What is the maximum voltage between two parallel conducting plates separated by \(2.5 \space \text {cm}\) of dry air?
(A) \(75 \space \text {MV}\)
(B) \(75 \space \text {kV}\)
(C) \(75 \space \text {cV}\)
(D) \(75 \space \mu \text {V}\)
There is something wrong with this question.
