Expert Answer
Ans-
Parallelogram law of addition
If 
and 
are the two vectors to be added, a diagram is drawn in which the tail of coincides with the tails of . Taking these two as the adjacent sides we complete the parallelogramABDC, where 
= and 
= . The diagonal through the common tails gives the sum of the two vectors. i,e + = 
, where is the diagonal through the common tails.
