Which expression correctly describes the radioactive decay of a substance whose half-life is T?

The half-life of a radioactive isotope is 6.5 h. If there are initially 48 * 10³² atoms of this isotope, the number of atoms of this isotope remaining after 26 h is:

Two protons are separated by 10^-16 m. The nuclear (N), electrostatic (E), and gravitational (G) forces between these protons when written in order of increasing strength are:
