A 8.01-nC charge is located 1.95 m from a 4.06-nC point charge.
(a) Find the magnitude of the electrostatic force that one charge exerts on the other.
(b) Is the force attractive or repulsive?

  • physics -

    Coulomb’s Law
    F = k •q1•q2/r²,
    k =9•10^9 N•m^2/C^2
    q1 = 8,01•10^-9 C,
    q2 = 4.06•10^-9 C,
    r =1.96 m
    repulsive force
