$A$ force $\vec{F} = 2\hat{i} + b\hat{j} + \hat{k}$ is applied on a particle and it undergoes a displacement $\vec{S} = \hat{i} - 2\hat{j} - \hat{k}$. What will be the value of $b$,if the work done on the particle is zero?

  • A
    $0$
  • B
    $\frac{1}{2}$
  • C
    $\frac{1}{3}$
  • D
    $2$
