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. (a) Find the magnetic field (magnitude and direction) produced by the two charges at point P if (i) υ’ = υ/2; (ii) υ’ = υ; (iii) υ’ = 2υ. (b) Find the direction of the magnetic force that q exerts on q', and find the direction of the magnetic force that q' exerts on q. (c) If υ = υ’ = 3.00 × 105 m/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?
