It states that ‘If two vectors are completely represented by two adjacent sides of a parallelogram, then the diagonal of the parallelogram from the tails of two vectors gives their resultant vector’. Draw the second vector using the same scale from the tail of the first vector. So, we have. This is the resultant in vector. Treat these vectors as the adjacent sides and complete the parallelogram. How To Perform Experiment. “, Addition of Two Vectors in Components Form. Parallelogram Law of Vectors. Resolution of a Vector into Two Components: We can also use the parallelogram law to determine the components of a vector along any two arbitrary axes. R is the resultant of A and B. R = A + B.

Consider the two vectors again. [2] Using a parallelogram to add the forces acting on a particle on a smooth slope. How To Perform Experiment. Theory. Parallelogram law of forces apparatus (Gravesand’s apparatus), plumb line, slotted weights, thin strong thread, white drawing, paper sheet, drawing pins, mirror strip, pencil, set square/ protractor, a body whose weight is to be determined. Let θ be the angle between P and Q and R be the resultant vector. Then the quantities and are said to satisfy the parallelogram law if Animation. Magnitude and Direction of Resultant: law of parallelogram of forces The sum of the vectors is obtained by placing them head to tail and drawing the vector from the free tail to the free head. Statement of the parallelogram law. Click the mouse over each step to see the flash animation of this procedure. Let P and Q be two vectors acting simultaneously at a point and represented both in magnitude and direction by two adjacent sides OA and OD of a parallelogram OABD as shown in figure.. Let θ be the angle between P and Q and R be the resultant vector.Then, according to parallelogram law of vector addition, diagonal OB represents the resultant of P and Q. Parallelogram Law of Vectors.

The parallelogram law of vector addition is implemented to calculate the resultant vector. Q8: State parallelogram law of vector addition. Then the quantities and are said to satisfy the parallelogram law if given by the third side taken in reverse order.”, The parallelogram law of vector addition states Parallelogram Law of Vectors Objective Our objective is to find the weight of a given body using the Parallelogram Law of Vectors. They are represented in magnitude and direction by the adjacent sides OA and OB of a parallelogram OACB drawn from a point O.Then the diagonal OC passing through O, will represent the resultant R in magnitude and direction. Following are steps for the parallelogram law of addition of vectors are: Draw a vector using a suitable scale in the direction of the vector. Let denote the norm of a quantity.
