Determine the intense electric field if the charge is acted upon by a force of 12 N, and the charge itself is equal to 3 C.

We calculate the strength of a given electric field by the formula:

E = F / q, where F is the force with which a given electric field acts on the charge (by the condition F = 12 N), q is the magnitude of the charge (by the condition q = 3 C).

Let’s perform the calculation:

E = F / q = 12/3 = 4 N / Kl = 4 V / m.

Answer: The strength of a given electric field is 4 N / C (4 V / m).
