Question

State parallelogram law of vector addition? Find analytically the resultant R of two vector A and B inclined at an angle? What is the resultant R if both A and B are parallel to each other.

Answer 1

Answer:

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. Now, expand A to C and draw BC perpendicular to OC. ... Direction of resultant: Let ø be the angle made by resultant R with P.

Answer 2

Answer:

Here's your answer

Explanation:

According to parallelogram law of vector addition if two vectors are acting on two sides of parallelogram then tge corresponding diagonal represents the resultant of two vectors.

If A and B are parallel vectors then angle between them is 0°

R=√(A^2+B^2+2AB cos 0°)

R=√(A^2+B^2)
