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 ≈í¬±)/(M1 + M2¬¨‚â ) m/sec
B. g(M1 - M2 sin ≈í¬±)/(M1 + M2¬¨‚â ) m/sec¬¨‚â§
C. g(M2 + M1 sin ≈í¬±)/(M1 + M2¬¨‚â ) m/sec¬¨‚â§
D. g(M2 ‚àö√≥ M1 sin ≈í¬±)/(M2 - M1¬¨‚â ) m/sec¬¨‚â§
Answer» C. g(M2 + M1 sin ≈í¬±)/(M1 + M2¬¨‚â ) m/sec¬¨‚â§
