What is the strength of the electric field at the point at which a force of 20 mN acts on the 4.0 mC charge from the side of the field?
To find out the value of the field strength at a point with a charge of 4 mC, use the formula: E = F / q.
Data: F – force from the side of the field (F = 20 mN = 2 * 10-2 N); q is the charge at the specified point (q = 4 mC = 4 * 10-3 C).
Calculation: E = 2 * 10-2 / (4 * 10-3) = 5 N / C or 5 V / m.
Answer: At the indicated point in a charge of 4 mC, the field strength, according to the calculation, is 5 N / C (5 V / m).
