A 200-N/C electric field is in the positive x direction. The force on an electron in this field is: A) 200 N in the positive x direction B) 200 N in the negative x direction C) 3.2 *10^-¹⁷ m/s², in the positive x direction D) 3.2 * 10^-¹⁷ m/s², in the negative x direction E) 0

Question

Quizplus · Accepted Answer

The force on a charge in an electric field is given by F = qE. For an electron, q = -1.6 x 10^-19 C. Thus, F = (-1.6 x 10^-19 C)(200 N/C) = -3.2 x 10^-17 N, which is in the negative x direction.
