Question

Calculate the magnitude and direction of the Coulomb force on each of the three charges shown in the figure above.

1)The force on the 6 uC charge,and the direction of the force on the 6 uC charge:
2)The force on the 1.5 uC charge,and the direction of the force on the 1.5 uC charge:
3)The force on the -2 uC charge,and the direction of the force on the -2 uC charge:

Answer 1

am I doing this rite? if the distance between 91 and 92 is 3 cm??

F12 = k (6*10^-6)(1.5*10^-6) / .0009 ----> 90 N???
