Question 2

A research team is investigating electrostatic forces in low-Earth orbit where atmospheric molecules are sparse. Two spherical satellites, each carrying a net positive charge, experience a repulsive electrostatic force of 8.2 × 10⁻⁴ N when separated by 120 m. Mission planners propose doubling the charge on one satellite while reducing the separation distance to 60 m. Describe how Coulomb's Law predicts the change in electrostatic force between the satellites under the proposed conditions.
