Two blocks of equal mass are released on...

Two blocks of equal mass are released on two smooth sides of a duble inclined plane with a fixed base as shown in the figure. If each angle of inclination is `45^(@)`, the acceleration of the centre of mass of the system of the two blocks is (Acceleration due to gravity `=10" ms"^(-2)`)

`10 ms^-2` vertically downward.

`10 ms^-2` vertically upward.

`5 ms^-2` vertically downward

`5 ms^-2` vertically upward.
