Please answer and show work . Thx

1. What is the magnitude of the electrostatic force experienced by one elementary charge at a point in an electric field where the magnitude of the electric field strength is 3.0 x 10' newtons per coulomb? 2. A charged particle is placed in an electric field E. If the charge on the particle is doubled, the magnitude of the force exerted on the particle by the field E is 3. How much energy is needed to move one electron through a potential difference of 1.0 x 10- volts? 4. In an electric field, 6.0 joules of work are done to move 2.0 coulombs of charge from point A to point B. Calculate the potential difference between points A and B. 5. Calculate the potential difference across a 6-ohm resistor if 4 joules of work are required to move 2 coulombs of charge through the resistor
