Calculating Torque on an Apple: Fx, Fy, Fz

[Weatherwizard]

What is the magnitude of the torque about the origin of an apple at coordinates (-3.0, 0, 7.0) m due to force F whose only component is Fx = 2.0 N?
What is the y-component of this torque?
What is the magnitude of the torque if the force is Fx = - 2.0 N?
What is the y-component of this torque?
What is the magnitude of the torque if the force is Fz = 2.0 N?
What is the y-component of this torque?

t=Ia or is there another equation?


t=-3*2.0 N= -6 N*m
I did N*m for the other ones but still getting the answer wrong.

If (-3.0, 0, 7.0) is a point in 3D space (x,y,z) then...

t=-3*2.0

is that T = x * F ?

I believe that should be T = z * F

Draw it.
