Field strength at some point 0.2 kN / C. Determine the magnitude of the force with which the field at this point will act on a charge of 2.25 μC.

The strength of the electric field E at some point in space is defined as the ratio of the force F, which acts on the charge q placed at this point, to the value of this charge, that is

E = F / q.

From this formula we define the force F:

F = E * q.

To calculate the force, it is necessary to take into account that:

E = 0.2 (kN / C) = 0.2 * 10 ^ 3 (H / C);

q = 2.25 (μC) = 2.25 * 10 ^ -6 (C).

Substitute the obtained numerical values of E and q into the formula for F:

F = E * q = 0.2 * 10 ^ 3 * 2.25 * 10 ^ -6 = 4.5 * 10 ^ -3 (H).

Answer: F = 4.5 * 10 ^ -3 (H).
