Question

state parallelogram law of addition of vectors. write an expression for the magnitude and direction of resultant of two vectors inclined to each other. when is the resultant maximum and minimum? what is centipetal accleration ? derive expression for it?​

Answer 1

Answer:

Triangle law of vector addition states that "when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector. "

Resultant acts in the direction making an angle α=tan−1(P +Q cosθQ sinθ) with direction of vector P .

The resultant of two forces acting on the same point is maximum when the forces are acting in the same direction and minimum when they operate in opposite direction.

The property of the motion of a body traversing a circular path is called Centripetal Acceleration.

The unit of centripetal acceleration is m/s2.
