- Homework Statement
- Consider the central force ##F (r) = - k / r^2 ˆr ## to which a particle of mass m is subject; where ˆr is the unit vector along the line connecting the center of forces with the position of the particle. Calculate the torque that F exerts on m and the angular momentum of the particle;

Calculate the torque that F exerts on m and the angular momentum of the particle;

both quantities with respect to O

- Relevant Equations
- τ= r x F L=rxp

HI

τ= r ˆr x - ##k / r ^ 2## ˆr= 0 right? since ˆr x ˆr is zero

What about L?

τ= r ˆr x - ##k / r ^ 2## ˆr= 0 right? since ˆr x ˆr is zero

What about L?
