Parallelogram Law of Vectors State parallelogram law of vector addition- As per this law, the summation of squares of lengths of four sides of a parallelogram equals the summation of squares of length of the two diagonals of the parallelogram. if two vectors are considered to be the adjacent sides of a parallelogram, then the resultant of the two vectors is given by the vector that is diagonal passing … scalars are shown in normal type The diagram above shows two vectors A and B with angle p between them. Complete parallelogram OACB using the set squares and join OC. It state that “If two forces acting simultaneously on a particle, be represented in magnitude and direction by two adjacent sides of a parallelogram then their resultant may be represented in magnitude and direction by the diagonal of the parallelogram, which passes through their point of intersection.” In Euclidean geometry, it is necessary that the parallelogram should have equal opposite sides. On a Gravesand's apparatus, if the body of unknown weight (say S) is suspended from the middle hanger and balancing weights P and Q are suspended from othe two hangers then.
