# Question - 1.

A vessel is completely filled by a liquid of density $\rho$ as shown in figure having acceleration $g$ in horizontal direction. After getting equilibrium condition a particle of density $\frac{\rho}{2}$ is released from bottom of vessel at distance $x$ as shown in figure such that it reaches to water-air interface after time $\sqrt{\frac{2h}{g}}$. Assume all collisions with wall are completely elastic. Which of the positions satisfy the given situation

$A)$ $x=0$

$B )$ $x=h$

$C)$ $x=\frac{h}{9}$

$D)$ $x=\frac{h}{4}$  Note by Nishant Rai

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Oh yes, I have seen this problem. This is a multiple correct problem. The answer is a,b,c if I remember right.

Correct! This question came in my mock test, and i am still unable to solve it.

Getting options a and b is relatively easy. You just need to use the concept of effective acceleration due to gravity.

can you please write the solution. (i tried, but in vain )

I have not gotten it either. One of my friends showed me this problem and I failed to get answer. I tried now and I still havent gotten it. :/
