Figure shows two point charges, q and q', moving relative to an observer at point P. Suppose that the lower charge is actually negative, with q'=-q.
Part A: Find the magnitude of the magnetic field produced by the two charges at point P if v'?=v/2.
Part B: Find the magnitude of the magnetic field produced by the two charges at point P if v'=v.
Part C: Find the magnitude of the magnetic field produced by the two charges at point P if v'=2v.
Part D: Find the direction of the magnetic force that q exerts on q'.
Part E: Find the direction of the magnetic force that q' exerts on q.
Part F: If v=v'=3.00 x 105m/s, what is the ratio of the magnitude of the magnetic force acting on each charge to that of the Coulomb force acting on each charge?
