Physics JAMB 2005 If the distance between two point charges its increased by a factor of four, the magnitude of the electrostatic force between them will be
 Correct Answer: Option BExplanationFor the two point charges, the magnitude of the electrostatic force between them is given by the equation:F ∝ 1/r2, and if the distance is increased by a factor of 4, that is new distance = 4r, then, new force F ∝ 1/(4r)2 = ∝ 1/16r2 Thus it will be 1/16 of the former value Report an Error Ask A Question Download App Recommended textbooks for you College Physics Author:Raymond A.
