Question

. (I)State triangle law of vector addition.Find analytically the magnitude and direction of resultant of two vectors.   (II) Also find the resultant when the two vectors are in same direction, opposite direction and perpendicular to each other. 

​

Answer 1

Answer:

If 2 vectors acting simultaneously on a body are represented both in magnitude and direction by 2 sides of a triangle taken in an order then the resultant(both magnitude and direction) of these vectors is given by 3rd side of that triangle taken in opposite order

I think it is answer
