g has maximum value at the equator

If f(x) =x^(3)-3x has maximum value at x=a, then a=

Which of the following has the maximum value of electronegativity?

Show that (log x)/(x) has a maximum value at x=e

Assertion : The difference in g at the poles and the equator of the earth is directly proportional to the square of its angular velocity. Reason : The value of g is minimum at the equator and maximum at poles.
