To solve the problem of calculating the mass of the particle given the uncertainties in position and velocity, we can use Heisenberg's Uncertainty Principle. Here’s a step-by-step solution: ### Step 1: Understand Heisenberg's Uncertainty Principle Heisenberg's Uncertainty Principle states that the product of the uncertainties in position (Δx) and momentum (Δp) is greater than or equal to a constant: \[ \Delta x \cdot \Delta p \geq \frac{h}{4\pi} \] where \( h \) is Planck's constant. ### Step 2: Relate momentum to mass and velocity ...
