Explanation / Answer

v = 5.9 x 10^7 m/s k

q = -1.6 x 10^-19 C

u0 = 4pi x 10^-7

(A) r = 0.02i and |r| = 0.02 m

B = (u0 q / 4pi) (v x r) / |r|^3

B = 2.36 x 10^-15 T (-j)

Ans: (0, -2.36 x 10^-15 T , 0 )

(B) r = 0.01 k

B = 0

Ans: (0, 0 , 0)

(C) r = 0.01j + 0.01k |r| = 0.0141 m

B = 3.37 x 10^-15 i

Ans: (3.37 x 10^-15, 0 , 0 )
