Question

Two forces of 3 N and 4 N act on a body simultaneously and the forces are perpendicular to each other. What is the net force on the body?

Answer 1

`5N`

Explanation:

Let the forces be
`F_1=3N` and `F_2=4N`

Here both of the force is acting perpendicular
hence the net force
`F=sqrt(F_1^2+F_2^2`
`F=sqrt(3^2+4^2)=sqrt(9+16)=sqrt25`
`F=5N`
