Well, gosh, that makes sense! thanks!

I'd like to check my thinking which is getting fuzzy: Question: Two particles are fixed to an x axis: particle 1 of charge q1 = 2.91 x 10-8 C at x = 26.3 cm and particle 2 of charge q2 = -5.82q1 at x = 46.6 cm. At what coordinate on the x-axis is the electric field produced by the particles...

Thanks, but can you clarify the substitution? I callled the unknown charges Q and Q + 2q because 2q is what one sphere had extra before it discharged to the other sphere. I'm not sure what the qs are in your substitution...q2 is 2q minus q1? The new charges are q2 and q1?

I have attempted this problem twice and have one more chance before I get the "red ex" so I thought I'd check my thinking. Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.136 N when their center-to-center separation is 65.0 cm. The...

Ah, yes, thank you so much!

I'm working with Coulomb's law, and finding the force from known charges is easy. But I don't know how to find mass from Coulomb's law, and I guess I don't know an equation that will help. Two equally charged particles, held 3.8 x 10-3 m apart, are released from rest. The initial...
