Answer:
4.30 x 10⁵ N/C
Explanation:
Two positive +3.0-μC point charges at opposite corners of the square creates equal and opposite electric field at the center. hence the electric field by these two positive charges at opposite corners becomes zero.
= length of the square of side = 0.50 m
= distance of the center from each corner =
Magnitude of net electric field at the center is given as
Answer:
First Question
Second Question
The wavelength is for an X-ray
Explanation:
From the question we are told that
The width of the wall is
The first excited state is
The ground state is
Gnerally the energy (in MeV) of the photon emitted when the proton undergoes a transition is mathematically represented as
Here h is the Planck's constant with value
m is the mass of proton with value
So
=>
Generally the energy of the photon emitted is also mathematically represented as
=>
=>
=>
Generally the range of wavelength of X-ray is
So this wavelength is for an X-ray.
