Question

Given two vectors A= 4.00i + 7.00jand B= 5.00i-2.00ja.Find the magnitude of each vector.b.Find the vector differenceC= A –B, give its magnitude and direction. c.Draw the vector A, B and C.d.Find the scalar product of A.B e.Find the vector productD= A x B, draw D and give its magnitude.

Answer 1

Step-by-step explanation:

C=A-B

=(4.00i+7.00j)-(5.00i-2.00j)

= -1.00i+9.00j

A.B=AxBx+AyBy

=(4 x 5)+(7 x -2)

=20-14

=6
