[Solved] What happens to the plates of the apparatus if we measure alternating charge using a Gold-leaf oscilloscope?

What happens to the plates of the apparatus if we measure alternating charge using a Gold-leaf oscilloscope?

a) It doesn’t diverge at all
b) It diverges momentarily
c) The plates give a proper divergence
d) The degree of divergence increases and decreases repeatedly

Answer: c
Explanation: The divergence of the plates of the Gold-leaf oscilloscope depends only on the presence of a charge, not on the quality of charge i.e. positive or negative. So, if the charge changes from positive to negative and vice versa the degree of divergence of the plates remains the same.
