Question
What will be the effect on inductive reactance XL and capacitive reactance XC if frequency of ac source is increased?
✓

Answer

The inductive reactance $\text{X}_{\text{L}}=\omega\text{L}=2\pi\text{vL}$ will increase with the increase of frequency v, while capacitive reactance $\text{X}_{\text{C}}=\frac{1}{\omega\text{C}}=\frac{1}{2\pi\text{vC}}$ will decrease with the increase of frequency v.

In 1959 Lyttleton and Bondi suggested that the expansion of the Universe could be explained if matter carried a net charge. Suppose that the Universe is made up of hydrogen atoms with a number density N, which is maintained a constant. Let the charge on the proton be: ep = -(1 + y)e where e is the electronic charge.
Show that the velocity of expansion is proportional to the distance from the centre.
