Which of the following is the correct formula of ground run distance with respect to aircraft weight?

SG= ( frac{WV_{LOF}^2}{2g[F_N+D+ mu (W-L)]_{0.7V_{LOF}^2}} )

SG= ( frac{WV_{LOF}^2}{2g[F_N-D+ mu (W-L)]_{0.7V_{LOF}^2}} )

SG= ( frac{WV_{LOF}^2}{2g[F_N+D- mu (W-L)]_{0.7V_{LOF}^2}} )

SG= ( frac{WV_{LOF}^2}{2g[F_N-D- mu (W-L)]_{0.7V_{LOF}^2}} )
