NEET Physics Simple Harmonic Motion MCQ Question
Consider a diagram of a U-tube containing mercury with one end connected to a suction pump and the other end open to the atmosphere. When the suction pump is removed, the mercury column executes simple harmonic motion. Which physical parameter is primarily responsible for this motion?
Pressure difference between the mercury columns
Viscosity of the mercury
Temperature of the surroundings
Mass of the mercury column
Correct Answer
Detailed Explanation
The simple harmonic motion of the mercury column in the U-tube is due to the pressure difference established between the two columns when the suction pump is removed, as described in Chunk 2 of the provided NCERT context.
