In a thunderstorm, charge is separated through a complicated mechanism that is ultimately powered by the Sun. A simplified model of the charge in a thundercloud represents the positive charge accumulated at the top and the negative charge at the bottom as a pair of point charges.       where x = 2.30 km; Q1 = +43.0 C; Q2 = −20.0 C   What is the electric field produced by the two point charges at point P, which is just above Earth’s surface? Enter a positive answer if the electric field is upward and a negative answer if the electric field is downward. Treating Earth as a conductor, what sign of charge would accumulate on the surface near point P?
