(chatquestion)...The potential at a point x (measured in um) due to some charges situated on the x-axis is given by V(x) = 20/(x² – 4) volts. The electric field E at x = 4 µm is given by: 5/3 volt/um and in the -ve x direction 5/3 volt/um and in the +ve x direction 10/9 volt/um and in the -ve x direction 10/9 volt/um and in the +ve x direction
