Here is an example on how to solve a vector question:
Example #1:
A force of 3N acts at an angle of 90 degrees to a force of 4N. Find the magnitude and direction of there resultant R.
( Note: a line similar to the 3N was drawn on right to make the vector tail to head. The resultant line R was then drawn from the tail of 4N line to Head of 3N line on right. Also note that direction in this case is the unknown angle. )
Answer
Using Pythaoras' theorem to find magnitude.
