Calculate the uncertainty in the velocity of a wagon of mass 3000 kg, whose position is known to an accuracy of `+- 10` pm.
Hint `:` Position known to accuracy means `+- 10` pm, i.e., `Delta x = +- 10` pm.

Explanation

To calculate the uncertainty in the velocity of a wagon of mass 3000 kg, given that its position is known to an accuracy of ±10 picometers, we can use Heisenberg's uncertainty principle. Here is a step-by-step solution:

### Step 1: Understand the given data
- Mass of the wagon (m) = 3000 kg
- Uncertainty in position (Δx) = ±10 picometers = ±10 × 10^-12 meters = ±10^-11 meters

### Step 2: Write down Heisenberg's uncertainty principle
According to Heisenberg's uncertainty principle, the relationship between the uncertainty in position (Δx) and the uncertainty in momentum (Δp) is given by:
