1.	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.
Answer» SOLUTION :As `F=(1)/(4PI epsi_(0)) E^(2)/r^(2)` so `[e^(2)/(2epsi_(0))]=[Fr^(2)]`, i.e., `e^(2)/(2epsi_(0)ch)=[(Fr^(2))/(ch)] rarr [M^(0)L^(0)T^(0)]`
