Question

why did the girls in Wanda's school surround her in the school yard? explain their behaviour​

Answer 1

Answer:

Explanation:

As the two force quantities are vevtors, so we will add them through vector law of addition.

Resultant vector= under root a^2 +b^2 +2abcostheta

Since the angle between them is 90 (cos90=0)

Resultant vector = under root a^2 +b^2

a=3N. b=4N

Resultant vector = 5N (magnitude
