Question

Define the vectors u = ai + bj and v = 4i - 3j. Determine the values of a and b if u is a unit vector and is perpendicular to v. a = 0.6 b = 0.8 a = 4 b = 3 a = 0.8 b = 0.6 none of the choices a = 3 b = 4

          Define the vectors u = ai + bj and v = 4i - 3j. Determine the values of a and b if u is a unit vector and is perpendicular to v.

a = 0.6
b = 0.8

a = 4
b = 3

a = 0.8
b = 0.6

none of the choices

a = 3
b = 4
