A force F^{\to} acts on a particle having position vector r^{\to} (with respect to origin). It produces a torque \tau^{\to} about origin, choose the correct option:-

Correct Answer is : →r.→τ=0and→F.→τ=0

r^{\to}.\tau^{\to} >0 \and F^{\to}. \tau^{\to}

r^{\to}.\tau^{\to} =0 \and F^{\to}. \tau^{\to}=0

r^{\to}.\tau^{\to} =0 \and F^{\to}. \tau^{\to}\neq0

r^{\to}.\tau^{\to} \neq0 \and F^{\to}. \tau^{\to}=0
