Question

Calculate the value of the electric field when the the filed point is located at 3 centimetre from the point charge . The charge of the point charge is 4nC

Answer 1

Calculate the force exerted on a test charge by an electric field. ... Thus the magnitude of the electric field, E, for a point charge is ... Here Q = 2.00 × 10−9 C and r = 5.00 × 10−3 m
