T torque
r = 0.1m (distance between the axis of rotation and point where the force acts)
F₁ = 10 N
|T| = r F₁
|T| = 0.1 10 = 1Nm
If force F₁ acts to the right of point A, then the torque is trying to turn the meterstick clockwise.
There is a lot of guessing involved in this answer. The real equation for torque is:
\(\vec \tau = \vec r \times \vec F\)
You should always post the given figure together with your question.
