Question

with the given first example,
Find the magnitude of the magnetic force: FB =|q| vB sin

        = (1.60 x10-19 C)(7.00 x106 m/s)(0.025 T)(sin 60°)
        = 2.425 X10-14 N

A proton moves with a speed of 4.10 X106 m/s horizontally, at a right angle toa magnetic field. What magnetic field strength is required to justbalance the weight of the proton and keep it movinghorizontally? with the given first example,

Explanation / Answer

equilibrium=> mg = BeVcos90 = BeV => the magnetic field : B = mg/eV = 1.67x10^-27*9.8/(1.6x10^-19*4.1x10^6) =2.495x10^-14 T
