    Charge and Voltage on Capacitors.

    This is an example problem from one of my lectures, and I was not sure how they arrive to the solution. Originally the C23 capacitor, was C2 and C3 capacitors in parrallel. They combined them into Ceq by additing them two.

    Coulomb's Law and Electrical Fields

    Oh, I completely forgot about that, and then it will be Tcosθ, and you find T using the mg=Tsinθ the euqation there fore will be F(electrical)- Tsinθ-mgcosθ= 0 and you solve for F(electrical) F(electrical) = qE and then you look for q

    Coulomb's Law and Electrical Fields

    Is it the force due to the other charge, which will be + and equalt to kq^2 / r^2... and I would find R using sinθSorry, I mized it with other problem. What other force there could be?
