Question - 1.

A vessel is completely filled by a liquid of density ρ\rho as shown in figure having acceleration gg in horizontal direction. After getting equilibrium condition a particle of density ρ2\frac{\rho}{2} is released from bottom of vessel at distance xx as shown in figure such that it reaches to water-air interface after time 2hg\sqrt{\frac{2h}{g}}. Assume all collisions with wall are completely elastic. Which of the positions satisfy the given situation

A) A) x=0x=0

B)B ) x=hx=h

C) C) x=h9x=\frac{h}{9}

D) D) x=h4x=\frac{h}{4}

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.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

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.
