Finding length of vector with unknown variable.

Purely for study purposes.

Find the smallest possible length of the vector →v .

Let vector V = (-2/3,b,16/7)

when i work out the equation as per normal i get Sqrt(50/21+b^2)

Is it possible to work out the unknown variable in this question? I don't think it is but please correct me if I'm wrong

**Equation for finding length of vector :**Sqrt(a^2+b^2+c^2)Question would be quite straight forward had there been no unknown variable but since there is i am quite stuck.when i work out the equation as per normal i get Sqrt(50/21+b^2)

Is it possible to work out the unknown variable in this question? I don't think it is but please correct me if I'm wrong
