PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question

Question

If the electric field at a point is 3.0 x 10^5 N/C directed to the right, what is the force on an electron (q = -e) placed at that point?
Options
A Directed to the right.
B Directed to the left.
Correct Answer
C Zero, because electrons are negative.
D Directed perpendicular to the field.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The force on a negative charge is always in the opposite direction of the electric field vector (F = qE).

Hint

Force direction for negative vs positive charges.
