Question

A piece of paper remains afloat in air at the same position. If its mass is 0.001kg, what is the amount of upward buoyancy that it experiences?

Answer 1

The upwards buoyancy experienced by the paper with a mass of 0.001kg is 0.0098 N, which equals the gravitational force acting on it, allowing it to float.

Step-by-step explanation:

If a piece of paper is remaining afloat in the air at the same position, the amount of upward buoyancy it experiences must equal the gravitational force pulling it downward. Given that the mass (m) of the paper is 0.001kg, and the acceleration due to gravity (g) is approximately 9.8m/s2, we can calculate the weight (W) of the paper as W = m × g = 0.001kg × 9.8m/s2 which equals 0.0098 N. Thus, for the paper to remain afloat, the buoyant force must also be 0.0098 N, effectively balancing out the weight of the paper.
