Question

The force applied to a conductor is 10N if the charge in the conductor is 5C, what is the electric field intensity?

(a) 10V/m

(b) 2V/m

(c) 3V/m

(d) 15V/m

I have been asked this question by my college director while I was bunking the class.

My question is taken from Electric Field Strength and Electric Flux Density topic in division Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

Right choice is (b) 2V/m

For explanation I would say: Electric field intensity is the force per unit charge. The formula is:

E = F/Q = 10/5 = 2V/m.
