Answer #1

Given

= velocity of charge = 75000 i - 49000 j

= (0.250 - 0 ) i + (- 0.250 - 0 ) j + (0 - 0 ) k = 0.250 i - 0.250 j + 0 k

|r| = sqrt (0.250^{2} + (- 0.250)^{2}) = 0.353
m

magnetic field is given as

= (/4) (q) ( x ) /r^{3}

= (10^{-7}) (- 3.4 x
10^{-6}) ((75000 i - 49000 j ) x (0.250 i - 0.250 j + 0
k))/(0.353)^{3}

= (10^{-7}) (- 3.4 x
10^{-6}) (- 6500 k) /(0.353)^{3}

= 0 i + 0 j + (5.024 x 10^{-8})
k

= 0 i + 0 j + 0.05024 uT k
