Question

If vector a is 4i -3j and b vector is 6i +8j then find magnitude and direction of vector B-vectorA

Answer 1

Answer:

The direction is from B to A

The direction is from B to AMagnitude = root [ 29 ]

Explanation:

Vector A = 4i - 3j

Vector B = 6i + 8j

Vector A - Vector B = 4i - 3j - ( 6i + 8j)

= - 2i + 5j

Magnitude of vector A - Vector B =

root [ (-2)^2 + (5)^2 ]

root [ 4 + 25 ]

root [ 29 ]

Vector BA is written as Vector A - Vector B

Therefore The direction is from B to A
