Electrostatic repulsion is the force between two charges having the same sign, that tends to separate them further. The force is proportional to the product of the charges, and inversely proportional to the square of the distance between them.
You use more significant figures. 5 sigfigs (1.0985) is more accurate than 2 sigfigs (1.0)
The formula that links voltage (V), resistance (R) and current intensity (I) is

Solve this formula for I to get

Plug your values for V and R and you'll get the current.
