If uncertainty principle is applied to an object of mass 1 milligram, ...
Explanation:

The uncertainty principle, also known as Heisenberg's uncertainty principle, states that it is impossible to simultaneously determine both the position and momentum (or velocity) of a particle with absolute certainty. The more accurately we try to measure one of these quantities, the less accurately we can know the other.

Given:
Mass of the object = 1 milligram = 1 x 10^(-6) kg

Formula:
The uncertainty principle is given by the formula:
Δx * Δp ≥ h/4π
where Δx is the uncertainty in position, Δp is the uncertainty in momentum, and h is the Planck's constant (h = 6.626 x 10^(-34) J s).

Calculating the uncertainty in momentum:
Since momentum is given by the product of mass and velocity (p = mv), we can write the uncertainty in momentum as:
Δp = m * Δv
where Δv is the uncertainty in velocity.

Calculating the uncertainty in position:
The uncertainty in position can be calculated using the formula:
Δx = h/4πΔp

Substituting the given values:
Δp = (1 x 10^(-6) kg) * Δv
Δx = (6.626 x 10^(-34) J s) / (4π * (1 x 10^(-6) kg) * Δv)

Simplifying the equation:
Δx * Δp = (6.626 x 10^(-34) J s) / (4π * (1 x 10^(-6) kg) * Δv) * (1 x 10^(-6) kg) * Δv
Δx * Δp = (6.626 x 10^(-34) J s) / (4π)
Δx * Δp = 5.27 x 10^(-35) J s

Converting the units:
1 J = 1 kg m^2/s^2
Δx * Δp = 5.27 x 10^(-35) kg m^2/s^2

Final answer:
The uncertainty value of velocity and position for an object of mass 1 milligram is 5.27 x 10^(-35) kg m^2/s^2. Therefore, the correct answer is option C: 0.52 x 10^(-28) m^2 s^(-1).
