An average human weighs about If two such generic humans each carried 1.0 coulomb of excess charge, one positive and one negative, how far apart would they have to be for the electric attraction between them to equal their weight?

Explanation:

excess charge, q1 = 1 C, q2 = - 1 C

Let the distance is r.

let your mass is, m = 50 kg

Weight, W = mass x gravity = 50 x 9.8 = 490 N

Use the Coulomb's law

r = 4285.7 m

r = 4.285 km

the independent variable, or the one that is intentionally manipulated is the speed.

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
