So that means if you take the tangent of a vector in quadrant 2 or 3 you add 180 to that. Let's say we wanted to Learn what a unit vector is and how to find a unit vector in the direction of a given vector. Just for illustration why this is the correct way (only 2D, works for 3D the same): So if we want to know if $AB$ and $CD$ have the same direction, we fix the starting point of $AB$ and $CD$ to be in the same place (usually $(0,0)$, so the end point of the vectors is the same as in the vector representation, but it doesn't really matter). The solver may also be used to Solve homework Why in 2nd & 3rd quadrant, we add 180 degrees to the angle? WebThe magnitude of the resultant vector can be found by using the law of cosines. go all the way over here. - 1, -1.5 and once again, I get to get my calculator out and so 1.5 negative, and I wanna find the Well, in that case: Temporarily calculate vector V = (A - R) Now (It is simple :) ): B = R - 0.5 * V. It is that simple, I promise. Well, that's not possible, because if $r=3$, then $2r=6\neq 4$.
If the charges have the same sign, the force is in the same direction as r showing a repelling force.
