Question 47

Electrostatics

If the force on a charge of 0.2 coulomb in an electric field is 4 N, then the electric field intensity of the field is

  1. A.0.8
  2. B.0.8 N/C
  3. C.20.0 N/C
  4. D.4.2 N/C
  5. E.20.0 C/N
Show the answer and explanation

Answer: C (20.0 N/C)

Explanation

E = F/q = 4/0.2 = 20 N/C.
