The height is
Explanation:
The acceleration due to gravity is
The height where the particles will meet is
The distance travelled by the particle from the bottom is
The distance travelled by particle from the top is
Apply the equation of motion,
The time when they will meet is
For the particle from the bottom
For the particle from the top
Therefore,
So,
