What is the magnitude (physics)? Help solve please?
Guys, please help me prepare for the test!! How do I do this?
Vector A=28m. Vector B points 20.015° east of north. Vector C points 20.015 west of north. A+B+C=0 (Hint: this is a symmetrical problem. Don't til the coordinate system).
What is the magnitude of B and C?
Thanks so much, best answer gets 10!
Ps the answer is 14.9m for both.

Does vector A by any chance point south???
Then the magnitudes of B and C must be equal. The cancellation of north components has it that
2 * x * cos(20.015°) = 28 m
x = 14.9 to 1 d.p.
