Question

Determine the vector which when added to the

resultant of A= 2i -4j- 6k and B =4i +3j+ 3k

gives the unit vector along z-axis.​

Answer 1

Answer:

answer is -6i cap+j cap+4k cap

Explanation:

let the vector added be m

m+(2i cap-4j-6k+4i+3j+3k)=k

m=k-(6i cap-j cap-3 k cap)

= -6i cap+j cap+4 k cap
