Question

Chapter-18 Electric Forces and Electric Fields 1. One mole of a substance contains 6.02 x 1023 protons and an equal number of electrons. If the protons could somehow be separated from the electrons and placed in very small, individual containers separated by a million meters, what would be the magnitude of the electrostatic force exerted by one box on the other? A) 8.7 x 103N B) 9.5 x 104N C) 2.2 x 105N D) 8.4 x 107 N 1.6x108 N 2. Two particles of the same mass carry charges +30 and -20, respectively. They are shot into a region that contains a uniform electric field as shown. The particles have the same initial velocities in the positive x direction. The lines, numbered I through 5, indicate possible paths for the particles. If the electric field points in the negative y direction, what will be the resulting paths for these particles? 1 f 120 and nath 4 for -20
