A heavy block kept on a frictionless surface and being pulled by two ropes of equal mass m. At t = 0, the force on the left rope is withdrawn but the force on the right end continues to act.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

Options

A. `F_(1)=F_(2)=F` for `t lt 0`
B. `F_(1)=F_(2)=F+mg` for `t lt 0`
C. `F_(1)=F, F_(2)lt F` for `t lt 0`
D. `F_(1)lt F, F_(2)=F` for `t lt 0`

Answer

A
