How does the mass of an object change when it acquires negative charge? decrease

Question

How does the mass of an object change when it acquires negative charge? decreases increases doesn't change More information is needed. When combing your hair, you scuff electrons from the comb onto your hair. Is your hair then positively or negatively charged? What about the comb? positively charged; negatively charged Both are positively charged. Both are negatively charged. negatively charged; positively charged Neither is charged. What keeps an inflated balloon from falling down if you rub it against your hair and place it against a wall? Rubbing leaves a balloon electrically charged; the charged balloon polarizes the wall. Rubbing distorts the atoms inside the balloon and polarizes it. When you rub the balloon against your hair, the balloon may have some oil attached to it, which can be sticky. When you rub the balloon against your hair, it will remove some mass from the balloon and make it lighter. Rubbing polarizes the air inside of the balloon. Why are metal-spiked shoes not a good idea for golfers on a stormy day? The metal spikes can accumulate a net charge. The spikes attract electrical charges. There might be electrical sparks between the two spikes because they are conductors. The metal spikes provide an effective electrical path from cloud to ground. A neutral ball is suspended by a string. A negatively charged insulating rod is placed near the ball, which is observed to be attracted to the rod. This is because the ball becomes positively charged by induction. the ball becomes negatively charged by induction. the number of electrons in the ball is greater than in the rod. the string is not a perfect conductor. there is a rearrangement of the electrons in the ball. A charge of -1 coulomb is place at the 0-cm mark of a meter stick. A charge of -1 coulomb is placed at the 100-cm mark of the same meter stick. Is it possible to place a proton somewhere on the meter stick so that the net force on it due to the two charges is 0? Yes; to the right of the 50-cm mark Yes; to the left of the 50-cm mark Two charges q_1 and q_2 are separated by a distance d and exert a force F on each other. What new force F would exist if q_1 is halved? F = theta F = 1/2 F F = 4 F F = 1/4 F F = 2 F

Explanation / Answer
