1.	Figure shows three blocks of mass m each hanging on a string passing over a pulley. Calculate the tension in the string connecting A to B and B to C ?
Answer» Solution :NET pulling FORCE `= 2mg - mg = mg` Total mass `= m+m+m=3M` Acceleration, `a=(mg)/(3m)=(g)/(3)` Considering block A, `T_(1)-mg=ma` or `T_(1)=mg+ma` or `T_(1)=mg+m((g)/(3))` or `T_(1)=(4)/(3)mg`, Considering block C, `mg-T_(2)=ma`or `T_(2)=mg-ma` or `T_(2)=mg-(mg)/(3)=(2)/(3)mg`.
