Explanation / Answer

F = qvxB

F = -53 i -12 j -39 k

v = -6 i +7 j +6 k

B = Bx i +By j +Bz k

q = 1 c

F = q vxB

-53 i -12 j -39 k = 1*(-6 i +7 j +6 k)x(Bxi +By j +Bz k)

-53 i -12 j -39 k = i (7Bz - 6 By) +j(6Bx +6Bz)+ k(-6By -7Bx)

comparing with i, j , k components

-53 = 7Bz - 6 By ...(1)

-12 = 6Bx +6Bz .... (2)

-39 = -6By - 7Bx ...(3)

Bx = By ...(4)

from (1) , (2) and (3) , (4) we get

Bx = By = 3 T

Bz = -5 T

B = 3i +3j -5 k
