Charges/electric field

  1. Jan 28, 2004 #1
    Suppose that the strength of the electric field about an isolated point charge has a certain value at a distance of 1 m. How will the electric field strength compare at a distance of 2 m from the point charge?

    i think the field strength will be 1/4 at twice the distance. am i correct?

    Right. The field from a point charge follows an inverse square law: [itex]E = \frac{kq}{r^2}[/itex]
