QUESTION #51 Magnetic Lorentz Force
An electron moves through a uniform magnetic field vecB = B_0hati + 2B_0hatjmathrm\ T. At a particular instant of time, the velocity of electron is vecu = 3hati + 5hatjmathrm\ m/s. If the magnetic force acting on electron is vecF = 5ehatkmathrm\ N, where e is the charge of electron, then the value of B_0 is ______ mathrmT.
