What are the magnitude and direction of the electric field at a point midway between a -7.0 µC and a +6.0 µC charge 2.5 cm apart? Assume no other charges are nearby.

  • physics - ,

    At the midway point, the distance is r = 0.0125 m from each charge.

    The fields due to each charge are in the same direction at points in between.

    Coulomb's law tells you that the E-field due to a charge q is

    E = k q/r^2

    Add the fields of each charge. You may need to look up the Coulomb constan,t k.

    a) What is the magnitude of the electric field at a point midway between a −8.5μC and a +8.5μC charge 8.0cm apart? Assume no other charges are nearby.
    b) What is the direction of the electric field?
