Find the resultant of two vectors P = 3 i + 2 j a

Question

Find the resultant of two vectors P = 3 i + 2 j and Q = 2 i + 3 j. In solution of this question to find resultant they have directly added P and Q and then found magnitude of it. But they have not used the formula for finding resultant that is / P^2 + Q^2 + 2PQ cos(angle)

both are the same thing you can also do it by formula or you can add them and then get the magnitude the 2ndformula is bascially derived from the 1stone only

Find the resultant of two vectors P = 3 i + 2 j and Q = 2 i + 3 j.

In solution of this question to find resultant they have directly added P and Q and then found magnitude of it. But they have not used the formula for finding resultant that is \/ P^2 + Q^2 + 2PQ cos(angle)

Mam today in neet ug 2021 due to my nervousness I bubbled one wrong figure of my roll number but I have filled the roll number correctly in the blocks the invigilator adviced me to leave it as it is and to bubble the same correct figure so I did that .am very much worried what will happen
