A solenoid of length 16 cm consists of closely spaced coils of wire wrapped tightly around a wooden core. The magnetic field str
ength is 2.5 mT inside the solenoid near its center when a certain current flows through the coils. If the coils of the solenoid are now pulled apart slightly, stretching it to 18 cm without appreciably changing the size of the coils, what does the magnetic field become near the center of the solenoid when the same current flows through the coils

Explanation:
To ionize the hydrogen atom
So the required energy is as
So
We have to calculate the energy required to ionize hydrogen atom when it is in n=5
So the energy should be less than
