Electric field from a point charge
WebTo detect an electric field of a charge q, we can introduce a test charge q 0 and measure the force acting on it. F → = 1 4 π ε 0 q q 0 r 2 r ^. Thus the force exerted per unit charge is: E → = F → q 0 = 1 4 π ε 0 q r 2 r ^. Note that the electric field is a vector quantity that is defined at every pint in space, the value of which is ...
