Answer to Question #292671 in Physics for haasggdfnsd

Question

. The diagram below shows the behavior of the electroscope before and after a positively charged rod is placed near the electroscope knob. This tells us that the movement of electrons is from ____. A. Rod to leaves C. Knob to leaves, then back to knob B. Leaves to knob D. Leaves to knob, then back to leaves 2. A glass rod was positively charged when rubbed with a silk cloth. The net positive charge is accumulated because the glass rod __________. A. loses protons B. loses electrons C. gains electrons D. loses electrons 3. Gravitational forces and electric forces are both ________________. A. forces with attractive and repulsive behaviors B. indirectly proportional to the square root of separation between bodies C. directly proportional to the product of the masses and charges D. decreasing when the distance between two bodies is decreasing

Answer 1

1: This tells us that the movement of electrons is from knob to leaves, then back to knob.

2: The net positive charge is accumulated because the glass rod loses electrons

3: Gravitational forces and electric forces are both directly proportional to the product of the masses and charges
