A small solid ball of density `rho` is held inside at point A of a cubical container of side L, filled with an ideal liquid of density `4rho` as shown in the figure. Now, if the container starts moving with constant acceleration a horizontally and the ball is released from point A simultaneously, then choose from following the correct option(s)

Options

A. For ball to hit the top of container at end `Q, a=3g`
B. For ball to hit the top of container at end `Q, a=2g`
C. Ball hits the top of container at end Q after a time `t=sqrt(L/(3g))`
D. Ball hits the top of container at end Q after a time `t=sqrt((2L)/(3g))`

Answer

B, C
