Answer:
The energy in its ground state is 10 meV.
Explanation:
It is given that,
The energy of the electron in its first excited state is 40 meV.
Energy of the electron in any state is given by :
![E=\dfrac{n^2\pi^2h^2}{8mL^2}](https://tex.z-dn.net/?f=E%3D%5Cdfrac%7Bn%5E2%5Cpi%5E2h%5E2%7D%7B8mL%5E2%7D)
For ground state, n = 1
.............(1)
For first excited state, n = 2
.............(2)
Dividing equation (1) and (2), we get :
![\dfrac{E_1}{40}=\dfrac{1}{4}](https://tex.z-dn.net/?f=%5Cdfrac%7BE_1%7D%7B40%7D%3D%5Cdfrac%7B1%7D%7B4%7D)
![E_1=10\ meV](https://tex.z-dn.net/?f=E_1%3D10%5C%20meV)
So, the energy in its ground state is 10 meV. Hence, this is the required solution.
The answer to the question is True
I beleive she isnt doing any work due to holding the box motionless, you must be exerting a force in the direction of the box motion. If she is just standing there holding the box their isn't no work becuase no distance has been covered. work = force = distance.
No I don’t think so. But it worth a try tho. Try it out.
