We are able to obtain fairly large currents in a conductor because(a) The electron drift speed is usually very large(b) The number density of free electrons is very high and this can compensate for the low values of the electron drift speed and the very small magnitude of the electron charge(c) The number density of free electrons as well as the electron drift speeds are very large and these compensate for the very small magnitude of the electron charge(d) The very small magnitude of the electron charge has to be divided by the still smaller product of the number density and drift speed to get the electric current
 
 
 
 
The force between point charges kept in vacuum is 18 Newton. If a glass plate of dielectric constant 6 is placed between these charges, then the value of force will be:
Two long straight parallel conductors separated by a distance of $0.5m$ carry currents of $5A$ and $8A$ in the same direction. The force per unit length experienced by each other is
Free $^{238}U$ nuclei kept in a train emit alpha particles. When the train is stationary and a uranium nucleus decays, a passenger measures that the separation between the alpha particle and the recoiling nucleus becomes $x$ in time $t$ after the decay. If a decay takes place when the train is moving at a uniform speed $v,$ the distance between the alpha particle and the recoiling nucleus at a time $t$ after the decay, as measured by the passenger will be:
