## Homework Statement

a point particle is located in the position r=i+2j m . A gravitation (vertical) force of 1.5N acts on the particle. The torque about the origin is...

## Homework Equations

thau = r X F = rFsin(theta)

## The Attempt at a Solution

it's 0 right?

magnitude r = sqrt(1^2+2^2)m

mag(r).1.5N.Sin(180)=0
