An irregular shaped non conductor has some charge distribution. The potential difference between the two points A and B in it is V. If it is now enveloped in an spherical non conducting shell having uniform charge distribution in it, the new potential difference between the points (neglect any induction due to presence of charge)

If A and B are two independent events, then the probability of occurrence of at least one of A and B is given by 1- P(A') P(B').

Two identical conducting rods are first connected independently to two vessels, one containing water at 100^@C and the other containing ice at 0^@C .
