State whether the statements are True or False.
The probability of an occurrence of event A is .7 and that of the occurrence of event B is .3 and the probability of occurrence of both is .4.
Considering Earth's potential as 0 is nothing but an assumption.We assume that Earth is a collection of infinte negative charge and it can even supply more charges to it.As earth has such a huge amount of negative charge with capacity to be supplied with even more any other body will be positive w.r.t Earth.Hence we assume its potential to be zero.
As Earth can store unlimited charge its capacitance is infinity
As C is infinity V has to be 0.
Hope this solved your query

Two polaroids P1 and P2 are placed in a crossed position. Unpolarised light of intensity I0 is incident on P1. If P2 is rotated through an angle ө about the direction of propagation of light, keeping P1 fixed,
Any even number has a general form of 2x(where x is any positive integer)
Take cube of the number that is cube of 2x
So 8 multiplied with any number is even
Hence cube of any number is even
So the given statement is true
