The Answer of An exam paper contains the following equation for rocket propulsion: $( M + \Delta m ) v = M ( v + \Delta v ) + \Delta m \left( v + v _ { e } \right)$ . The error in the equation is that,instead of (v + v_e),the velocity of the fuel relative to the ground should be A)-v_e. B)+v_e. C)v - v_e. D)v_e-0 v. E)2v_e.

An Exam Paper Contains the Following Equation for Rocket Propulsion (M+Δm)v=M(v+Δv)+Δm(v+ve)( M + \Delta m ) v = M ( v + \Delta v ) + \Delta m \left( v + v _ { e } \right)(M+Δm)v=M(v+Δv)+Δm(v+ve​)
