No entiendo, ¿me ayudan?

¿Con que fuerza se atraen dos cargas q1= 50 μC y q2= -100 μC, si estan separas 2 mm?

K= 9 x 10^9 m2 N/C2

    Eso se resuelve con la Ley de Coulomb

    Fuerza = F = K ( q1 * q2 ) / r^2

    Donde K es una constante (K= 9 x 10^9 m2 N/C2), q1 y q2 son los valores de las cargas y r es la distancia que separa a q1 de q2.

    r= 2mm

    r=2x10^-3m

    F= ( 9 x 10^9 (50 x10 ^-6 * -100x10^-6) ) / (2x10^-3) ^2

    F= (9 x 10^9 (-5x10^-9 )) / ^

    F= - 45/9 x 10^9

    F= - 11250000 N

    F= - 11.25x10^6 N ....el signo es por el sentido

    salu2 y suerte
