When the same charge spreads in the foil of the electroscope then there is a repulsion between the similarly charged foil.
Explanation:
An electroscope is a device which has metallic foil inside a sealed glass flask preventing in form external environmental disturbances. There is a ball connected to the foil via a conductor.
When the ball is touched by a charged body then the charge is conducted from the body to the ball via conductor to the foils of the electroscope. When the same charge spreads in the foil of the electroscope then there is a repulsion between the similarly charged foil.
When the charge is supplied to any metallic body then it spreads over the surface of the metal so as to minimize the force of repulsion between the similar charges.
The Big Crunch hypothesis is a symmetric view of the ultimate fate of the universe. Just as the Big Bang started as a cosmological expansion, this theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.
The formula that is usually used for the calculation of power is the product of force applied and the speed at which the action is done. That is, P = Fv We let d be the distance covered and the equation for power would be, P = (500 N)(d/240 s) P = 2.08d
