Question

State parallel law of vector addition and determine magnitude and direction of resultant vector.​

Answer 1

Answer:

According to the parallelogram law of vector addition if two vectors act along two adjacent sides of a parallelogram(having magnitude equal to the length of the sides) both pointing away from the common vertex, then the resultant is represented by the diagonal of the parallelogram passing through the same common vertex ...

Answer 2

Answer:

According to,

$\tt{Parallelogram \: law : }$

• Vector addition if two vectors act along two adjacent sides of a parallelogram(having magnitude equal to the length of the sides) both pointing away from the common vertex, then the resultant is represented by the diagonal of the parallelogram passing through the same common vertex and in the same sense as the two vectors.
• Using triangle law of vector addition proves the parallelogram law of vector addition.
• Also, find the magnitude of the resultant vector using cosine law.
