O yes O no Submit My Answers Give UpExplanation / Answer
A) Magnitude of vector A = -2i + 4j + 6k
= sqrt(2^2 + 4^2 + 6^2)
= 7.48
B) Magnitude of B = sqrt(4^2 + 2^2 + 3^2)
= 5.38
C) A - B = (-2i + 4j + 6k) + (4i + 2j - 3k)
= 2i + 6j + 3k
D) magnitude = sqrt(2^2 + 6^2 + 3^2) = 7
E) the magnitude will be same
