17. Potential due to a point charge: What is the electric potential 17.0 cm from a 3.50 μC point charge?

  • Physics -

    V = -k Q/R

    k is the Coulomb's Law constant
    = 8.99*10^9 N*m^2/C^2
    Q = 3.50*10^-6 C
    R = 0.17 m

    Solve for V, which will be in J/C units

  • Physics -

    So because of the negative sign in the question would the answer end up being negative?

  • Physics -

    I meant to say the negative sign in the equation.
    And Thank you very much.

  • Physics -

    I was wrong about the negative sign. Relative to zero voltage at infinity, the potential at nonzero distances will be positive.
