Two masses $M_1$ and $M_2$ are attached to the ends of a light string which passes over a massless pulley attached to the top of a double inclined smooth plane of angles of inclination $\alpha$ and $\beta$. The tension in the string is :
817-1003

  • A
    $\frac{M_1 M_2(\sin \beta+\sin \alpha) g}{M_1+M_2}$
  • B
    $\frac{ M _2(\sin \beta) g}{ M _1+ M _2}$
  • C
    $\frac{M_1(\sin \alpha) g}{M_1+M_2}$
  • D
    $Zero$
