1. After plastic rod that has been charged to -0.035 uC (microC) touches a metal surface, -0.022 uC remain. What kind of charged particle was transferred and in which direction? How many charged particles were transferred?2. Consider an insulating sphere of radius R that has a total positive charge Q distributed uniformly throughout its volume. Calculate the total electric flux through a closed spherical surface with radius r<R. Calculate the total flux for a spherical surface with radius r>R.
