Field strength at some point E = 0.4 N / C. Determine the magnitude of the force F

Field strength at some point E = 0.4 N / C. Determine the magnitude of the force F with which the field at this point will act on the charge q = 4.5 μC.

These tasks: E (field strength at some point) = 0.4 N / C; q (amount of charge taken) = 4.5 μC (4.5 * 10-6 C).

The force with which the field at some point acts on the charge is equal to the product of the field strength and the charge value: F = q * E.

Calculation: F = 4.5 * 10-6 * 0.4 = 1.8 * 10-6 (1.8 μN).

Answer: A force of 1.8 μN will act on the charge.
