b) increases slightly
c) decreases slightly
d) remains constant
Homework Equations
The Attempt at a Solution
I know weight is nothing but gravitational force exerted on the body and it acts vertically downward. If a body is charged by rubbing one is positive and other is negative. I also know weight varies from place to place since W = mg, and the value of g vary from place to place. So when charged by friction one has more protons(positive charged body) and other has less number of protons(negative charged body), so when used in the formula weight may changed. So i feel the answer is weight may slightly increase or slightly decrease, that is option (a). Am i correct?
