charge on each alpha particle = +2e
 
hence Coulomb force  F = begin mathsize 14px style fraction numerator 2 e cross times 2 e over denominator 4 πε subscript straight o space straight r squared end fraction space equals space 9 cross times 10 to the power of 9 space end exponent cross times fraction numerator 4 cross times 1.6 cross times 1.6 cross times 10 to the power of negative 38 end exponent over denominator 10 to the power of negative 30 end exponent end fraction space almost equal to 922 space space N end style
