Excess electrons are placed on a small lead sphere so that its net charge is -3.20x10-9C. How many excess electrons are there on the sphere

f is prop to m1xm2 double m1 double force

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
