Two masses `m_(1)=4kg and m_(2)=2kg` are connected with an nextansible , massless string that passes over a frictionless pulley and through a slit as, shown the string is vertical upon by a conatant friction force 10 N by the slit as it moves (use `g=10m//s^(2)`

Options

A. Acceleration of mass `m_(1)` is `( 5)/( 3) m//s^(2)` , downwards
B. Tension in the string is same throughout
C. Force exerted by the string on mass `m_(2)` is `(70)/( 3) N`
D. If position of both the masses are interchanged, then 2 kg mass moves up woth an acceleration `( 10)/( 3) m//s^(2)`

Answer

A, C
