A -5.00nC point charge is on the axis at x= 1.20 m . A second point charge Q is on the x axis at -0.600m. What must be the sign and magnitude of Q for the resultant electric field at the origin to be 45.0 N/C in the +x direction?
How effective is this?
An electric force of 4.0 N exists between two objects separated from each other by a distance of r. If the distance is decreased to 0.50r, calculate the magnitude of the force between the two objects.
