The electric field intensity between two charged plates is 1.1*10^3 N/C. The plates are 0.070 m apart. What is the electric potential difference, in volts, between the plates?

physics
In a television picture tube, electrons are accelerated by an electric field having a value of 1*10^5 N/C. Find the force on an electron. so i know i use E=F/q to find the force but i need the q to get it how do i do that??
