Think back to Coulomb's Law. Two coins with identical charges are placed on a lab table 1.35 m apart.
If each coin experiences a force of 2.0 N because of the presence of the other coin, calculate the charge on each coin.

Question

eljaja · Answer

The equation my teacher gave me is
Fe = (Kq1q2)/d^2
and she said q1 would equal q2

Vocaloid · Answer

you are given the force and distance, solve for q1

since q1 and q2 you can replace q2 with q1 in the equation so the final equation only has one unknown

Vocaloid · Answer

*q1 = q2

eljaja · Answer

Okay. I think I understand. What would the equation be? I can do the rest from there.
