charges

Please show all work and diagrams plus equations used to solve problem. Thanks! 1) Particles 1, with charge q1 and 2, with a charge q2 are on the x axis, with particle 1 at x = a with and particle 2 at x=-2a. For the net force on a third charges particle, at the origin to be zero q1 and q2 must be related by q2=: (answer B ...continues

charge

Please show all work and diagrams plus equations used to solve problem. Thanks! 1) Experimentor A uses a test charge qsub0 and experimentor B uses a test charge 2qsub0 to measure an electric field produced by stationary charges. A finds a field that is: ans: The same as the field around B - WHY? 2) An isolated point ...continues

charges

Please show all work and diagrams plus equations used to solve problem. Thanks! Two point particles, with charges of q1 and q1 are placed a distance r apart. The electric field is zero at a point P between the particles on the line segment connecting them. We conclude that: (answer C - why) a) q1 and q2 must have the sa ...continues
