If gold were always sold by weight, could you make money buying gold at one altitude above the ground and selling it at a different altitude?
A) Yes, you could make money by buying gold at a lower altitude and selling it at a higher altitude. B) Yes, you could make money by buying it at either a lower or higher altitude, and then selling it at the other altitude. C) Yes, you could make money by buying gold at a higher altitude and selling it at a lower altitude. D) No, you couldn't make any money this way because the mass of the gold would be the same at both altitudes. E) No, you couldn't make any money this way because the weight of the gold would be the same at both altitudes.
Three point charges are placed on the x-axis. A charge of +2.0 ?C is placed at the origin, -2.0 ?C to the right at x = 50 cm, and +4.0 ?C at the 100 cm mark
What are the magnitude and direction of the electrostatic force that acts on the charge at the origin? (k = 1/4??0 = 8.99 × 109 N ? m2/C2) What will be an ideal response?
