Answer:
Explanation:
Given
When we drop an object from height , suppose h
it takes time T
using equation of motion
where
here because it dropped from a certain height
When height is increases to three times of original height
i.e.
then time period becomes
Answer:
Explanation:
For n-=1 state hydrogen energy level is split into three componets in the presence of external magnetic field. The energies are,
,
,
Here, E is the energy in the absence of electric field.
And
are the highest and the lowest energies.
The difference of these energies
is known as Bohr's magneton.
B=2.5 T,
Therefore,
Now,
Therefore, the energy difference between highest and lowest energy levels in presence of magnetic field is
