27.25 Two charges, QA and QB, are sepa- rated by a distance x. If we double the dis- tance between the charges and triple the magnitude of charge A, what happens to the magnitude of the force that charge A exerts on charge B? What happens to the magnitude of the force that charge B ex- erts on charge A?

Need help with the question 27.25 and 27.26, please and thank you!

e 27.25 Two charges, QA and QB, are sepa- rated by a distance x. If we double the dis- tance between the charges and triple the magnitude of charge A, what happens to the magnitude of the force that charge A exerts on charge B? What happens to the magnitude of the force that charge B ex- erts on charge A? F m th 27.26 A mad scientist invents a de- vice that is able to teleport every electron 2 in their body to the center of the Earth (6.37x106 m below). We can make the as- sumption that the human body is mostly water with a bit of carbon and as such there will be about 3.2 × 1026 electrons per kilogram of body. If the mad scientist, who weighs 65 kg is so unwise as to actu- ally use this device on himself what will the magnitude of the attraction between his body (stripped of all electrons) and all the electrons newly deposited at the cen- ter of the Earth? (How does this compare with the gravitational attraction between the mad scientist and the Earth?)
