Answer» search Type your question... 11th Physics Laws of Motion Solving Problems In Mechanics For mass m, the forces are given as T−mg=ma ...... (1) Similarly, for mass M, the forces are given as Mg−T=Ma ...... (2) From equation (1), we have T=mg+ma ...... (3) SUBSTITUTING equation (3) in (2) we get Mg−mg−ma=Ma G(M−m)=a(M+m) a=( M+m M−m
)g T=m×( M+m M−m
)g+mg T= M+m Mm−m 2
g+mg T=g( M+m Mm−m 2
+m) T=g( M+m Mm−m 2 +m 2 +Mm
)=g( M+m 2Mm
