The problem involves calculating the initial torque of a rod subjected to a force acting at its upper end. The rod is oriented along the y-axis and has a specified length, with the force expressed in vector form.
Some participants have provided hints regarding the definition of torque and suggested finding the expression for the position vector. The discussion is ongoing, with no clear consensus on the correct answer yet.
Participants are working within the constraints of the problem statement and the multiple-choice format, which may limit the exploration of potential solutions.

That's for you to figure out! All I did was give a definition of torque. Hint: Find an expression for \vec{r} (its magnitude is ℓ) and perform the cross product.shiby4444 said:What answer would that be with respect to my choices?
