Expert Answer:

mass of a protons is 1.67×10 −27  kg 

F space equals space G fraction numerator m 1 m 2 over denominator r squared end fraction space
space equals space fraction numerator 6.67 space cross times 10 to the power of negative 11 end exponent N m squared space k g to the power of negative 2 end exponent cross times open parentheses space 1.67 space cross times space 10 to the power of negative 27 end exponent close parentheses squared k g squared over denominator open parentheses 10 to the power of negative 15 end exponent close parentheses squared space m squared end fraction
equals 18.60 space cross times space 10 to the power of negative 35 end exponent space N space
