Question

( IN ADDITION TO THE EQUATIONS, PRESENT YOUR REASONING IN SENTENCES WITH ACTUAL NOUNS AND VERBS)- (WRITE UNITS FOR EVERY VALUE THAT YOU USE)-(PLEASE, WRITE NEAT)

Two small balls are hanging on two separate strings .12 m long attached to a common point. The mass of the balls is roughly 25 mg. They are given an identical charge (positive charge) and spread apart to a distance 0.015 m from each other.

1) Draw a freebody diagram for one ball.
2) Using Coulomb's Law, estimate how much charge is on a ball, assuming equal charge on each , q₁= q_2.
3) Estimate roughly how many electrons (fewer or extra) the ball needs to have such a charge.
