two equal vectors of magnitude 2A are inclime perpendicular to each other find the resultant and direction of vector.

Answer 1

2A sqrt(2) at an angle of 45o

Answer 2

You are given vectors A = 5.0i – 6.5j and B = -3.5i +7.0j. A third vector C lies in the xy-plane. Vector C is perpendicular to vector A, and the scalar product of C with B is 15.0. From this information, find the components of vector C.
