Diketahui : Ditanya V di x = 10 cm = 0,10 m ? Jawab: Jadi, potensial listrik di x = 10 cm adalah

Diketahui :

table attributes columnalign right center left columnspacing 0px end attributes row cell q subscript A end cell equals cell 3 cross times 10 to the power of negative 6 end exponent space straight C end cell row cell straight X subscript straight A end cell equals cell 0 comma 08 space straight m end cell row cell q subscript B end cell equals cell negative 5 cross times 10 to the power of negative 6 end exponent space straight C end cell row cell straight X subscript straight B end cell equals cell 0 comma 12 space straight m end cell end table   

Ditanya V  di x = 10 cm = 0,10 m ? 

Jawab:

table attributes columnalign right center left columnspacing 0px end attributes row cell V subscript C end cell equals cell V subscript A plus V subscript B end cell row blank equals cell fraction numerator k space q subscript A over denominator A C end fraction plus fraction numerator k space q subscript B over denominator B C end fraction end cell row blank equals cell k open square brackets fraction numerator q subscript A over denominator A C end fraction plus fraction numerator q subscript B over denominator B C end fraction close square brackets end cell row blank equals cell 9 cross times 10 to the power of 9 space open square brackets fraction numerator 3 cross times 10 to the power of negative 6 end exponent over denominator left parenthesis 0 comma 10 minus 0 comma 08 right parenthesis end fraction plus fraction numerator open parentheses negative 5 cross times 10 to the power of negative 6 end exponent close parentheses over denominator left parenthesis 0 comma 12 minus 0 comma 10 right parenthesis end fraction close square brackets end cell row blank equals cell 9 cross times 10 to the power of 9 space open square brackets 150 cross times 10 to the power of negative 6 end exponent minus space 250 cross times 10 to the power of negative 6 end exponent close square brackets end cell row blank equals cell negative 900 cross times 10 cubed end cell row blank equals cell negative 9 cross times 10 to the power of 5 space volt end cell end table   

Jadi, potensial listrik  di x = 10 cm adalah negative 9 cross times 10 to the power of 5 space volt
