In unit-vector notation, what is the net torque about the origin on a flea located at coordinates (-2.0, 1.0 m, 1.0 m) when forc
djverab [1.8K]

Answer:

Torque, \tau=3i+2j+4k

Explanation:

Given that,

Position of the flea, r=(-2i+j+k)\ m

Force acting on the flea, F=(-2j+k)\ N

We need to find the net torque about the origin on a flea located at coordinates. Its formula is given by :

\tau=r\times F

\tau=(-2i+j+k) \times (-2j+k)

On solving the cross product of r and F, we get :

\tau=3i+2j+4k

So, the net torque about the origin on a flea is 3i+2j+4k. Hence, this is the required solution.
