An electron in orbit around a (one proton) nucleus has a speed of about 106 m/s. deduce the equivalent current due to the motion of the electron and estimate the magnitude of the magnetic dipole moment of this one electron atom.

(a) (B)

Explanation:

We have given the the speed of the electron =10^6 m/sec

The time period of the electron is given by where r is the Bohr radius, which is equal to

So time period

(A) We know that current

(B) Magnetic moment is given by , where I is current and A is area

So

f=ma newton's second law 7x8=56n

3. dark matter

empty space could also be a simple vacuum
