Electric Forces and Fields questions, please help!
1. Charge A and Charge B are 2.2 m apart. Charge A is 1.0 Coulomb, Charge B is 2.0 Coulombs, and Charge C is 2.0 Coulombs and is located between Charges A and B and is in electrostatic equilibrium. How far from Charge A is Charge C?
2. Two equal positive charges, both q= 2.0 x 10^ -6 Coulombs, interact with a third charge, Q= 4.0 x 10^ -6 Coulombs. What is the magnitude of the electric force on Q? (In a coordinate plane, the two "q"s are on the y axis: the first one is .3 meters above the origin and the second one is .3 meters below the origin. Q is located .4 meters right of the origin (on the +x axis). this all makes one triangle, or two right triangles side by side.)
2. E= Electric Force/q Electric Force= Kc x q1xq2/(r^2) E= Kc x q/(r^2) Kc= 8.99 x 10^9
3. I haven't gotten much accomplished besides a picture, I'm completely lost! D:
