Determine the modulus of force F acting on a point charge q = 4 nC, placed in a uniform electric field of strength E = 100 V / m

q = 4 nC = 4 * 10-9 Cl.

E = 100 V / m.

F -?

According to the definition, the strength of the electric field E is the vector force characteristic of the electric field, which is determined by the ratio of the force F, which acts on a charged body at a given point of the field to the value of this charge q: E = F / q.

F = E * q.

F = 100 V / m * 4 * 10-9 K = 400 * 10-9 N.

Answer: a point charge in an electric field is acted upon by a force F = 400 * 10-9 N.
