A 30 nC charge introduced into a given point of the field is affected by a force of 24 μN. Find the field strength at this point.

Initial data: q (the amount of charge that was introduced into a given point of the field) = 30 nC; F (force that acts on a given charge) = 24 μN.

SI system: q = 30 nC = 30 * 10-9 C; F = 24 μN = 24 * 10-6 N.

The field strength at the point where the given charge was applied can be determined by the formula: E = F / q.

Let’s calculate: E = 24 * 10-6 / (30 * 10-9) = 800 N / C.

Answer: The intensity at this point of the field is 800 N / C
