The uncertainties in the velocities of two particles A and B are 0.05 and 0.02

\mathrm{m}{\mathrm{s}^{ - 1}}

respecively. The mass of B is five times to that of mass A. What is the ratio of uncertainties

\left( {\frac{{\Delta {x_A}}}{{\Delta {x_B}}}} \right)

in their positions?

View answer and explanation

Correct option: A

Option A (2) is correct because the ratio of uncertainties in position is inversely proportional to the product of mass and uncertainty in velocity.
