Grade 11General Physics
Findthe resultant of two vectors of magnitude 5&3and making angle 60degree between them? Give the solution by using both triangle law and parallelogram law of vector addition. In my book its clearly given that R= P+Q = √P²+Q²+2PQcos∅.
But on adding the two vectors answer comes out as 8.
USing this formula √P²+Q²+2PQcos∅ answer comes out to be 7.
Explain
