According to the law of vector addition, When two vectors are added such that they are represented as two sides of a triangle in magnitude taken in the same order, then the third side represents the results of the two with order opposite of two.

In option c order of $\vec{2a}$ and $-\vec{2b}$ are same and thus third side represent the resultant of two.

Rx-st=r solve equation for s

dimulka [17.4K]

Rx - st = r

Rx = r + st Add st to both sides

Rx - r = st Subtract r from both sides

(Rx - r)/t = s Divide t on both sides ( to isolate s)
