Step 1: Write down the equation for electric field strength. Step 2: Rearrange for charge Q. Step 3: Substitute in values and calculate. Forces on Charges. The electric field strength equation can be rearranged for the force F on a charge Q in an electric field E: F = QE. Where: F = electrostatic force on the charge (N) Q = charge (C)

Calculate the acceleration of the proton when placed in a uniform electric field of field strength 6.0 × 10 –2 V m. Questions and model answers on 18.1 Electric Fields & Field Lines for the CIE A Level Physics syllabus, written by the Physics experts at Save My Exams.
An electric field is a region of space in which an electric charge “feels” a force. Electric field strength at a point is defined as: The electrostatic force per unit positive charge acting on a stationary point charge at that point. Electric field strength can be calculated using the equation: Where: = electric field strength (N C-1)
