  2. ...undefined 

Jawaban:

Diketahui:

begin mathsize 14px style r subscript Q 1 end subscript equals 15 space cm equals 0 comma 15 space straight m r subscript Q 2 end subscript equals 20 space cm equals 0 comma 2 space straight m Q subscript 1 equals 3 space μC equals 3 cross times 10 to the power of negative 6 end exponent space straight C Q subscript 2 equals negative 5 space μC equals negative 5 cross times 10 to the power of negative 6 end exponent space straight C k equals 9 cross times 10 to the power of 9 space bevelled fraction numerator straight N times straight m squared over denominator straight C squared end fraction end style 

Ditanya: begin mathsize 14px style V subscript Q 1 end subscript end style 

Jawab:

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row V equals cell k Q subscript 1 over r subscript Q 1 end subscript end cell row blank equals cell 9 cross times 10 to the power of 9 times fraction numerator 3 cross times 10 to the power of negative 6 end exponent over denominator 15 cross times 10 to the power of negative 2 end exponent end fraction end cell row blank equals cell fraction numerator 27 cross times 10 cubed over denominator 15 cross times 10 to the power of negative 2 end exponent end fraction end cell row blank equals cell 1 comma 8 space cross times 10 to the power of 5 space straight V end cell end table end style 

 

Jadi, jawaban yang tepat adalah begin mathsize 14px style 1 comma 8 space cross times 10 to the power of 5 space straight V end style.
