Explanation / Answer

v = 10^7*cos45i + 10^7sin45k

V = 0.7*1^7 i + 0.7*10^7 k

Fb = q*(V cross B )

Fb = 1.6e-19*( (0.7*1^7 i + 0.7*10^7 k) cross ( 0.4i )

Fb = 1.6e-19*0.7e7*0.4 j

Fb = 4.48e-13 j

Fb = ( 0 , 4.48*10^-13 , 0 )
-------------

b)

v = 10^7 -j

Fb = q*(V cross B )

Fb = 1.6e-19*( (10^7 -j) cross ( 0.4i )

Fb = 1.6e-19*1e7*0.4 k

Fb = 6.4e-13 k

Fb = ( 0 , 0 , 6.4*10^-13 )
-------------
