In which of the following mediums, will the force of attraction between the plates of a capacitor be greater?(a) Air(b) Water(c) Does not depend on the medium(d) Cannot be determinedThis question was addressed to me during an online interview.My doubt is from Force of Attraction Between Oppositely Charged Plates in division Capacitance and Capacitors of Basic Electrical Engineering
Answer» RIGHT answer is (b) Water The best I can explain: The absolute permittivity(epsilon) of water is greater than that of air. The EXPRESSION relating F and epsilon is F=epsilonA(V/x)^2/2. From this expression, we can see that as epsilon increases, the force of ATTRACTION also increases.
