Jawab :

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row F equals cell fraction numerator k Q subscript 1 Q subscript 2 over denominator r squared end fraction end cell row F equals cell fraction numerator 9 cross times 10 to the power of 9 cross times 5 cross times 10 to the power of negative 6 end exponent cross times 4 cross times 10 to the power of negative 6 end exponent over denominator open parentheses 3 cross times 10 to the power of negative 1 end exponent close parentheses squared end fraction end cell row F equals cell fraction numerator 9 cross times 5 cross times 4 cross times 10 to the power of 9 cross times 10 to the power of negative 6 end exponent cross times 10 to the power of negative 6 end exponent over denominator open parentheses 3 cross times 3 cross times 10 to the power of negative 2 end exponent close parentheses end fraction end cell row F equals cell fraction numerator 5 cross times 4 cross times 10 to the power of negative 3 end exponent over denominator open parentheses 10 to the power of negative 2 end exponent close parentheses end fraction end cell row F equals cell fraction numerator 20 cross times 10 to the power of negative 3 end exponent over denominator open parentheses 10 to the power of negative 2 end exponent close parentheses end fraction end cell row F equals cell 2 space straight N end cell end table end style 

Jadi, besar gayanya 2 N.
