Point charges of 0.24 uC and 0.45 uC are placed 0.35 m apart. What is the magnitude of the electric field, in newtons per coulomb, halfway between them?
Two stationary positive point charges, charge 1 of magnitude 3.60 nC and charge 2 of magnitude 1.90 nC, are separated by a distance of 46.0 cm. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the speed v_final of the electron when it is 10.0 cm from charge 1?
2. Calculate the electric force F. (magnitude and direction) between two point charges qi -10.0pC and q,-3.00 C if the distance r between them is 30.0 cm.
Two stationary positive point charges, charge 1 of magnitude 3.60 nC and charge 2 of magnitude 2.00 nC , are separated by a distance of 45.0 cm . An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the speed vfinal of the electron when it is 10.0 cm from charge 1? Express your answer in meters per second.
Two stationary positive point charges, charge 1 of magnitude 3.60 nC and charge 2 of magnitude 1.75 nC , are separated by a distance of 31.0 cm. An electron is released from rest at the point midway between the two charges, and it moves along the line connecting the two charges. What is the speed vfinal of the electron when it is 10.0 cm from charge 1? I keep following the calculations from the example problems here but my answer...

two point charges of magnitude positive 3 UC and -5 UC are placed along the x-axis at x equals 0 centimeters and y equals 40 cm respectively.where must a third charge q be placed along the x axis so that it does not experience any net force because of the other two charges.
Calculate the magnitude of the electric force between a 1.0 uC charge and a 2.0 uC charge that are separated by 3.0 m. Calculate the electric potential energy for the same situation. Hint: Make sure that you end up with appropriate units for all quantities instead of simply tacking the units on at the end.
6. When two point charges are moved further apart, the force between them decreases by a factor of 100. By what factor was their separation increased?
