What is the correct answer?


When a body of mass M1 is hanging freely and another of mass M2 lying on a smooth inclined plane(α) are connected by a light index tensile string passing over a smooth pulley, the acceleration of the body of mass M1, will be given by

A. g(M1 + M2 sin α)/(M1 + M2) m/sec

B. g(M1 - M2 sin α)/(M1 + M2) m/sec²

C. g(M2 + M1 sin α)/(M1 + M2) m/sec²

D. g(M2 × M1 sin α)/(M2 - M1) m/sec²
