Question 35

Electrostatics

Which of the following statements are true of an insulated charged body carrying a positive charge? I. It contains excess positive charges II. It creates an electric field III. It possesses potential energy IV. It carries electric current

  1. A.I and IV only
  2. B.I and II only
  3. C.I, II and III only
  4. D.I, II, III and IV.
Show the answer and explanation

Answer: C (I, II and III only)

Explanation

A positively charged body has more positive than negative charge, sets up an electric field and has electrical potential energy. Being insulated, its charge is at rest, so no current flows.
