At t = 0, the force on the left rope is withdrawn but the force on the right end continues to act. Let F and F, be the magnitudes of the forces by the right rope and the left rope on the block respectively. Fi = F2= F+ mg for t < 0 Fi < F, F2 < F for t> 0 (B) F = F2 F = F, F2 = F for t> 0 (A) = F for t < 0 %3D (C) (D)...(What does t<0 mean ?)
