Part A Situation. A 50 g insulating sphere carries a charge Q- 60 μC and is suspended by a silk thread from a fixed point. An external electric field which is uniform and vertical is applied. In the situation above, the applied electric field has a magnitude of 3000 N/c and is directed downward. The tension in the thread is closest to: 0.4N 0.7N 0.3N 0.5N 0.2N Correct
