A body of mass 10kg is hanging from another body of mass 15kg. The combination is pulled up by a string with an acceleration of . 1.2m−2 Find the tensions (in N) at A and B points as shown in figure (Take g=9.8m/s2).
275,110
we know that T=m(g+a)Tension at A is pulling the mass of 15+10 = 25kgSoTA=25(g+a)=25[9.8+1.2])=275NTB=10[g+a]=10[9.8+1.2]=110N
