Question

two forces on a praticle are perpendicular to each other and have magnitude 3N and 4N . Find the magnitude and the direction o the resultant force on the particle​

Answer 1

Explanation:

You can solve this through Pythagoras theorem

a^2+b^2=c^2

3^2+4^2=R^2 (In the case of vectors c is replaced by the resultant R)

9+16=R^2

25=R^2

R=√25

R=5N
