A uniform electric field of 2.00 kN/C is in the x direction. A positive point charge Q=3.00 mC is released from rest at the origin.
1. What is the potential dissimilarity between the origin and 4.00 m from the origin (V(4m)-V(0m))?
2. What is the change in the potential energy of the charge from x=0m to x=4m for the charge.
3. What is the kinetic energy of the charge if it moved from x=0m to x=4m without any loss of energy?
4. What is the potential V(x) as a function of x if V(x) is zero at x=0?
