A lift can move upward or downward. A light inextensible string fixed from ceiling of lift when a frictionless pulley and tensions in string `T_(1)`. Two masses of `m_(1) and m_(2)` are connected with inextensible light string and tension in this string `T_(2)` as shown in figure. Read the questionbs carefully and answer If `m_(1)=m_(2) and m_(1)` is moving at a certain instant with velocity `v` upward with respect to lift and the lift is moving in upward direction with constant acceleration `(a lt g)` then speed of `m_(1)` with respect to lift :A. `T_(1):T_(2):T_(3)::1:1:1`B. `T_(1):T_(2):T_(3)::6:5:3`C. `T_(1):T_(2):T_(3)::3:5:5`D. `T_(1):T_(2):T_(3)::6:5:6` |

Answer» Correct Answer - B `T_(1) mg=mxx2 thereforeT_(1)=mxx12` `T_(2)=mg T_(2)=mxx10` `mg-T_(3)=mxx4 T_(3)=mxx16` `T_(1):T_(2):T_(3)=6:5:3` |
