A particle with charge $-5\mathrm{.}90$ nC is moving in a uniform magnetic field vec$(B)=-(1\mathrm{.}23T)hat(k).$ The magnetic force on the particle is measured to be

vec$(F)=-(3\mathrm{.}90{10}^{-7}(N))hat(i)+(7\mathrm{.}60{10}^{-7}(N))hat(j)$

Part A

Are there components of the velocity that are not determined by the measurement of the force?

yes

no
