What magnitude of electric force will a 2.1 uC charge experience if it is placed in an electric field of magnitude 3.6 x 10^4 N/C?

A 4.5 u C point charge is released from rest in a uniform electric field of magnitude 1.47 x 10^4 N/C.  The mass of the charge is 2.8 x 10^-4 kg and the electric force is the only force present.  Find the speed of the charge when it has moved a distance of 0.65 m in this field.

Three point charges are on the x-axis.  Charge q1 = 7.6 uC is at the origin, q2 = -4.2 uC is at x = 0.40 m, and q3 = -3.1 uC is at x = 0.75 m.  Find the magnitude of the electric force acting on charge q3.

A 4.1 uC charge is placed in an electric field and, as a result, experiences an acceleration of 215 m/s^2.  If the mass of the charge is 1.2 x 10^-4 kg, find the magnitude of the electric field.  Assume that the electric force is the only force present.
