What is the force acting on a 0.5 C charge from the side of an electric field with a strength of 12V / m.

The electric field strength can be calculated using the formula:
E = F / q, where E is the strength of the electric field (E = 12 V / m), F is the force with which the electric field acts on the charge (H), q is the magnitude of the electric charge (q = 0.5 C).
Let us express and calculate the force of action on the charge:
F = E * q = 12 * 0.5 = 6 N.
Answer: A force equal to 6 N. acts on the charge.
