If coeffiecient of friction between the ...

If coeffiecient of friction between the block of mass 2kg and table is 0.4 then out acceleration of the system and tension in the string. `(g=10m//s^(2))`

Text Solution

Verified by Experts

Acceleration of the system `a=(4g-0.4(2g))/(6)=5.33m//s^(3)`
For the block of mass 4kg `4g-T=4(5.33)rArrT=18.68N`
