Question

When the area of cross section of the plate increases, what happens to the force between the plates?

(a) Increases

(b) Decreases

(c) Remains the same

(d) Becomes zero

I got this question in exam.

I need to ask this question from Force of Attraction Between Oppositely Charged Plates topic in section Capacitance and Capacitors of Basic Electrical Engineering

Answer 1

Right choice is (a) Increases

For explanation: The force of attraction between the two plates of the capacitor is directly proportional to the area of cross section of the plates, hence an area of cross section increases, the force of attraction also increases.
