Explanation / Answer

Note that

F = q v x B

Here, q = 1.602E-19, the charge of the proton.


PART A:

v = 1.0E7 m/s, x-z plane, 45 degrees with respect to the x axis.

Thus, in component form,

v = (7.071E6 i^ + 7.071E6 k^)

Here, B = 0.40i^ T

Thus,

F = qv x B

F = 4.53E-13j^ N

or

F = <0, 4.53E-13, 0> N [ANSWER]

**************************************************
PART B:

Here, v = -1.0E7j^ m/s

Thus,

F = q v x B

F = <0, 0, 6.41E-13> N

DONE! It was nice working with you!
