If two bodies of masses M1 and M2(M1 > M2) are connected by alight inextensible string passing over a smooth pulley, the tension in the string, will be given by

T = g(M2 - M1)/(M1 + M2)

T = g(M1 + M2)/(M1 × M2)

T = g(M1 - M2)/(M1 + M2)

T = g(M2 + M1)/(M2 - M1)

T = g(M2 - M1)/(M1 + M2)

T = g(M1 + M2)/(M1 × M2)

T = g(M1 - M2)/(M1 + M2)

T = g(M2 + M1)/(M2 - M1)
