    Find the dimension of the quantity (1)/(4pi epsilon_(0))(e^(2))/(hc) , the letters have their usual meaning , epsilon_(0) is the permitivity of free space, h, the Planck's constant and c, the velocity of light in free space.

    State whether the following statement is true or false. Give very brief reason in support of your answer. The quantity e^(2)/(2 epsi_(0) hc) is dimensionless. Here e, h and c are electronic charge, Planck's constant and velocity of light respectively and epsi_(0) is the permittivity constant of free space.
