Question

The addition of three vectors is done by
(a)Pythagoras theorem
(b)triangle law of vector addition
(c)polygon’s law of vector addition
(d)parallelogram law of vector addition

Answer 1

A) Pythagoras Theorem

I hope it will helps you✌️

Answer 2

Answer:

The magnitude of the resultant vector (R) can be determined using the Pythagorean theorem. As can be seen in these two examples, the resultant of the addition of three or more right angle vectors can be easily determined using the Pythagorean theorem. Doing so involves the adding of the vectors in a different order.
