Kinematics mcq question image

A. $$b + c = f$$

B. $$d + c = f$$

C. $$d + e = f$$

D. $$b + e = f$$

Answer : $$d + e = f$$

Solution :
If two non-zero vectors are represented by the two adjacent sides of a parallelogram, then the resultant is given by the diagonal of the parallelogram passing through the point of intersection of the two vectors
$$\therefore d + e = f$$
