An electron accelerated to 6.0 ´ 10⁶ m/s is deflected by a magnetic field of strength 0.82 T.  What is the force acting on the electron?  Would it be any different for a proton?         

F = Bqv = 0.82 T ´ 1.6 ´ 10^-19 C ´ 6.0 ´ 10⁶ m/s (P)

= 7.9 ´ 10^-13 N (P)

The value of the force would be the same (P)

But the direction would be opposite (P).
