Two blocks $\mathrm{A}$ and $\mathrm{B}$ of equal mass are released on two sides of a fixed wedge $\mathrm{C}$ as shown in the figure. Find the acceleration of the centre of mass of blocks $\mathrm{A}$ and $\mathrm{B}$. Neglect friction.

• Correct answer
  A

  $\frac{g}{2}$, downwards
• B

  $g$, downwards
• C

  $\frac{g}{2}$, upwards
• D

  $\frac{3}{4}g\text{,}$ downwards

Hence, the correct answer is option: 'A'.
