1) An initially non-charged gold leaf inside an electroscope has a total dimension of 2 [cm] x 4 [cm]. It is folded in half to have two equal squares of 2 [cm] x 2 [cm] on either side. 1a) A charged probe of +5*10^(-6) [C] is brought near the tip of the electroscope but does not touch. What effect do you predict will happen to the gold leaves and why? 1b) The same charged probe now makes contact to the electroscope and it's net charge is reduced to +2.5*10^(-6) [C] and the electroscope is removed. Explain what had happened and what is the surface charge density of each of the squares of the gold leaf? 1c) If the gold leaf squares are separated by an angle of 90 degrees, what is the magnitude of the electric force per area between the centers of the squares?
