Electrostatics - Forces in Combining Positive Charges

Not what you're looking for?

Two positive chrages, when combined, give a total charge of +8.7 micro Couloumbs. When the charges are seperated by 3.00 meters, the force exerted by one charge on the other has a magnitude of 8.30E-3 Newtons. Find the amount of each charge.

Solution Summary

The solution calculates the magnitude of electric charges.

Solution Preview

Let the charges be e1 and e2
e1+ e2= 8.7 micro Coulombs= 0.0000087 Coulomb

Force between the two charges when separated by 3 m = 8.3 E-3= 0.0083 Newtons

Force=e1 * e2 /(4 pi epsilon ...
