Figure shows a heavy block kept on a frictionless surface and being pulled on the left rope is withdrawn but the force on the right end continues to act. Let `F_1` and `F_2` be the magnitude of the forces by the right rope and the left rope on the block respectively. A. `F_(1)=F_(2)=F+mg` for `t lt 0`B. `F_(1) = F,F_(2)=F` for `t gt0`C. `F_(1)=F_(2)=F` for `t lt 0`D. `F_(1) lt F,F_(2)=F` for `t gt 0`
