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
R=
ans is 7 only …...you are adding vectors at an angle of 60 degree so you cannot directly add them
CAn you please explain what triangle law actually is. TO me its just addition of two vectors in consecutive order to find the resultant
The resultant would be of 7 magnitude.
ans should be7 because we cant add or subtracte a vector directly.and by using this formula u can add it and formula is (A)+(B)+2ABCOS60. THANK U........
