Question

Two Forces one vertical upwards and one horizontal to the left acts on an object. The magnitude of the vertical force is 45N and the magnitude of the horizontal force is 65N. Calculate the magnitude and direction of the net force acting on this object

Answer 1

Direction of net force= $-45i + 65j$

Magnitude= $\sqrt{45^2+65^2}$

Magnitude =$\sqrt{6250}$

Magnitude =79.06
