    Solution:What is the Electric Field for Two Point Charges on a Line?

    Homework Statement Consider two point charges placed on a line: q1=1.00uc_______<2m>_________P_______<2m>________q2=-1.00uc q1=1.00uc q2=-1.00uc r=2m a) Find the electric field E at the position P *hint: bring + at P. Ep=Ep1+Ep2 b) Using the above E, find the electric force on the charge...

    How Do You Calculate Electron Velocity in a Hydrogen Atom?

    Thanks for the help! I went back in the chapter and found the mass of the electron (don't know why this was not presented in the problem), used Coulomb's law to get the force, then found the velocity solving the square root of force x radius/mass. Thanks again!
