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?

Text Solution

Verified by Experts

Net force =2 mg -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_(2)=mg -(mg)/3=2/3mg`
