Math Problem Statement
A particle with charge − 5.20 nC is moving in a uniform magnetic field B⃗ =−( 1.25 T )k^ . The magnetic force on the particle is measured to be F⃗ =−( 4.00×10−7 N )i^+( 7.60×10−7 N )j^ . Part A Part complete Are there components of the velocity that are not determined by the measurement of the force?
