The settling velocity of a spherical particle of diameter less than 0.1 mm as per Stock’s law, is

A) $${{\text{V}}_{\text{s}}} = 418\left( {{{\text{G}}_{\text{s}}} - {{\text{G}}_{\text{w}}}} \right){\text{d}}\left( {\frac{{3{\text{T}} + 70}}{{100}}} \right)$$ B) $${{\text{V}}_{\text{s}}} = 418\left( {{{\text{G}}_{\text{s}}} - {{\text{G}}_{\text{w}}}} \right){{\text{d}}^2}\left( {\frac{{3{\text{T}} + 70}}{{100}}} \right)$$ C) $${{\text{V}}_{\text{s}}} = 218\left( {{{\text{G}}_{\text{s}}} - {{\text{G}}_{\text{w}}}} \right){{\text{d}}^2}\left( {\frac{{3{\text{T}} + 70}}{{100}}} \right)$$ D) $${{\text{V}}_{\text{s}}} = 218\left( {{{\text{G}}_{\text{s}}} - {{\text{G}}_{\text{w}}}} \right){\text{d}}\left( {\frac{{3{\text{T}} + 70}}{{100}}} \right)$$
