Question 10 (1 point) The electrostatic force between two charged particles is F. If the distance between the two particles is reduced by a factor of two and the charge on one of the particles is doubled, then the electric force will: 0 increase by a factor of 4 0 decrease by a factor of 4 0 increase by a factor of 8 0 remain the same Question 8 (1 point) A neutral metal rod is touched by a negatively charged metal sphere. Which of the following is true after the two come into contact? Select all that apply. 3 The sphere will be positively charged. 3 The sphere will be negatively charged. 3 The sphere will be neutral. 3 The rod will be positively charged. 3 The rod will be negatively charged. 3 The rod will be neutral. 3 This is an example of charging by conduction. 3 This is an example of charging by convection. 3 This is an example of charging by induction.
