What is the weight, in newton's, of an object on the surface of the earth with gravity accelerating it
at 9.8 m/s2?

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.
