Two vectors `P and Q` are inclined at an angle `theta and R` is their resultant as shown in the figure.
Keeping the magnitude and the angle of the vectors same, if the direction of `P and Q` is interchanged, then their is a change in which of the following with regard to R?
Options:
(a) Magnitude
(b) Direction
(c) Both magnitude and direction
(d) None of the above
