Aproton moves with a speed of 3.60 106 m/s horizontally, at a right angle to a magnetic field. what magnetic field strength is required to just balance the weight of the proton and keep it moving horizontally? (the mass and charge of the proton are 1.67 ✕ 10−27 kg and 1.60 ✕ 10−19 c, respectively.) b = t
