Question

11) Two vector P and Q are having magnitude of 3 and 3v3.Find the magnitude
of Resultant Vector if the angle between two vector is 90°​

Answer 1

Answer:

Magnitude of the resultant vector

| R| = √P^2+Q^2 + 2PQcostheta

|R| = √9+27+ 2PQcos90°

|R| = √36 +0

Therefore magnitude of resultant vector

|R| (assume) = 6

(cos 90° =0)
