JAMB Physics 1982 Question 32

Question 32

Electrostatics

As a positively charged rod is brought nearer to the top cap of a positively charged gold leaf electroscope, the divergence of the leaves will

  1. A.decrease to zero
  2. B.steadily increase
  3. C.decrease to zero and then increase
  4. D.remain constant
  5. E.increase to a maximum and then decrease.
Show the answer and explanation

Answer: B (steadily increase)

Explanation

The positive rod repels more positive charge down to the leaves, so they diverge more and more as it comes closer.
