Homework Statement
Two small, positively charged spheres have a combined charge of 5.4 x 10-5 C. If each sphere is repelled from the other by an electrostatic force of 1.04 N when the spheres are 2.2 m apart, what is the charge on sphere with the smaller charge?
Homework Equations
Coulombs equation = k(q1)(q2)/(r^2)=E
Force=(q)(E)
The Attempt at a Solution
Plugging in what I knew I got E=1.00301x10^-5, took that and plugged it in the force equation . . .1.04=q(1.00301x10^-5) and found q to be 1.03687x10^-5 since Q+q=5.4 x 10-5 and we know now q . . .I just found Q to be 4.36313x10^-5 . . .so doesn't that make 1.03687x10^-5 the answer?
