Pls answer and show work with formula. Thx a lot

7. If you place an electron and a proton near each other what happens? How does the force the proton exerts on the electron compare to the force the electron exerts on the proton? How do their accelerations compare? (Remember: the proton is 2000 times more massive.) 8. When sugar is poured from the box into the sugar bowl, the rubbing of sugar grains creates a static electric charge that repels the grains, and causes sugar to fly off in all directions (Have you ever noticed this?). If two sugar grains each acquire a charge of 3.0x 10- C at a separation of 8.0x10" m, with what force do they repel each other? 9. When spraying hairspray, some of the spreading out of the spray is due to the electrostatic charge on the hairspray droplets. If two droplets repel each other with a force of 9.0x10" N at a distance of 0.070 m, what is the charge on each of the equally charged drops of hairspray
