The space electrostatic space force space is
straight F equals straight k fraction numerator straight q subscript 1 straight q subscript 2 over denominator straight r squared end fraction equals 9 cross times 10 to the power of 9 cross times open parentheses 1.6 cross times 10 to the power of negative 19 end exponent close parentheses squared over open parentheses 20 cross times 10 to the power of negative 2 end exponent close parentheses squared
therefore straight F equals 5.76 cross times 10 to the power of negative 27 end exponent space straight N end style
