QUESTION 8 (Start on a new page.) Two metal spheres, P and T, on insulated stands, carry charges of +3 x 10° C and -6 x 10 C respectively. +3 x 10°C 8.1 The spheres are allowed to touch each other and are then placed 1,5 m apart as shown below. 8.2 8.3 8.4 -6 x 10°C II 1.5m In which direction will electrons flow while spheres P and T are in contact? Write down only FROM P TO T or FROM T TO P Calculate the net charge gained or lost by sphere P after the spheres have been in contact Calculate the number of electrons transferred during the process in QUESTION 8.2 A third sphere R, canying a charge of 3 x 10°C, is NOW placed between P and T at a distance of 1 m from T Calculate the net force experienced by sphere R as a result of its interaction with P and T.
