    Need to find force on a charge due to an electric field strenght, pls help

    i have a problem asking about a Electric potential field(V), form which i have to find the electric field strength vector(E). E=-(grad)V After i did this, it asks me to find the force on a charge at a point P. i know F=qE but this is when i have a E field due to a another charge on...
