9. The velocity of the disc when rolling begins can be obtained using the conservation of angular
momentum principle about the point through which the friction force acts. So, the coefficient of
friction has no bearing on final velocity. The work done by the force of friction will simply be
change in kinetic energy.

19. In a period the value of ionisation potential increases from left to right with breaks where the atoms
have some what stable configuration. In this case N has half filled stable orbital. Hence has highest
ionisation energy. Thus the correct order is B < C < O < N not B < C < N < O
20. Smaller the ion more is its ionic mobility in aqueous solution. Ionic radii of the given alkali metals
is in the order Na K Rb Cs and thus expected ionic mobility will be in the order
.Cs Rb K Na However due to high degree of solvation (or hydration) because of lower
size or high charge density, the hydrated ion size follows the order Cs Rb K Na and thus
conductivity order is Cs Rb K Na i.e. option (b) is correct answer.
