Explanation / Answer

Given :-

A = 105i

A x B = 74k

put the value of A in this equation

105i x B = 74k

i x B = 0.705k

magnitude of vector IBI = 0.705

direction of vectro B is j

B = 705j

a)

x component of vector B is

Bx = 0

b)

y component of vector B is

By = 0.705

c)

their is no z component of vector B

Bz = 0
