Question
State triangular law and parallelogram law of vector addition.
Solution
Triangle law of vector addition:
If two vectors acting on the particle at the same time are represented in magnitude and direction by the two sides of a triangle taken in one order, their resultant vector is represented in magnitude and directed by the third side of the triangle taken in opposite order.
Parallelogram law of vector addition:
If two vectors acting simultaneously at a point are represented in magnitude and direction by the two sides of a parallelogram drawn from a point, then their resultant is given by the diagonal of parallelogram passing through same point, both in magnitude and direction.
