How do you define mobility of a charge carrier in a conductor? Establish the following relation for mobility.
`mu = qtau//m`

Establish the following relation for drift velocity. V_d = (eE)/m tau

Define mobility of a charge carrier. What is its relation with relaxation time?

Define drift velocity of free electrons in a conductor across which a potential difference is applied. How is it related to mobility?

How do you represent the following by symbols in a floral formula?

What do you mean by permeability and susceptibility? How they are related with each other?

A man walking briskly in, rain with speed v must slant his umbrella forward making an angle theta with the vertical. A student derives the following relation between theta and v, tantheta = v and checks that the relation has a correct limit: as v rarr 0, theta rarr -0 , as expected.. (We are assuming there is no strong wind and that the rain falls vertically for a stationary man). Do you think this relation can be correct? If not, guess the correct relation.
