# (a) Use the Heisenberg uncertainty principle to calculate the uncertainty in energy for a corresponding time interval of (b) Compare this energy with the unification−of−forces energy and discuss why they are similar.

To determine

(a)

The uncertainty in energy for the given time interval using Heisenberg uncertainty principle.

Explanation

Given:

Uncertainty in time interval, Î”t=10âˆ’43â€‰s

Plank's constant, h=6.62Ã—10âˆ’34â€‰J-s

Formula used:

Formula to calculate the uncertainty in energy for the given time interval using Heisenberg uncertainty principle is,

â€ƒâ€ƒÎ”E=h4Ï€Î”t ...... (I)

Where,

• Î”E is uncertainty in energy.
• h is Plank's constant.
• Î”t is uncertainty in time interval.

Calculation:

Substitute 6.62Ã—10âˆ’34â€‰J-s for h and 10âˆ’43â€‰s for Î”t in equation (I).

â€ƒâ€ƒÎ”E=6

To determine

(b)

The relation between the uncertainty in energy and unification of force energy whether they are similar or not.
