The diagram above illustrates two charged bodies, X and Y separated by a distance r. Each body has charge q and mass m. Which of the following statements about the electrostatic force \(F_{e}\) and gravitational force \(F_{g}\) acting between the bodies is correct?
\(F_{e}\) is attraction while \(F_{g}\) is repulsion
Both \(F_{e}\) and \(F_{g}\) are that of repulsion
Both \(F_{e}\) and \(F_{g}\) is that of attraction
\(F_{e}\) is repulsion while \(F_{g}\) is attraction
Giải thích
electrostatic force can be repulsive or attractive and gravitational force is only attractive.
