QUESTION #51 Magnetic Lorentz Force
An electron moves through a uniform magnetic field B = B₀ i + 2B₀ j T. At a particular instant of time, the velocity of electron is u = 3 i + 5 j m/s. If the magnetic force acting on electron is F = 5e k N, where e is the charge of electron, then the value of B₀ is ______ T.
