I'm busy studying for my Physics exam this evening and I've come across a vector problem that I cant quite solve. Any help would be appreciated!
We are given the following vectors:
A = 5i - 6.5j
B = -3.5i + 7j
We are also told that a vector C lies in the xy-plane and is perpendicular to A. The scalar product of B and C is equal to 15. With this information we have to calculate the components of the vector C.
I have tried calculating the magnitude of B and then trying to solve the equation:
|B||C|cos{theta} = 15
But I didn't get very far. I have a feeling I'm just not seeing something and making a careless error.
Thanks in advance!
