1. The problem statement, all variables and given/known data A positively charged object is brought near to, but does not touch, one end of the a neutral metal rod on an insulated stand. The opposite end of the metal rod is grounded. The ground is removed, and then the positively charged object is removed. As a result of this procedue described above the metal rod will be : a) neutral b) have a net zero charge c) have a positive net charge d) have a negative net charge 2. When white light from the sun strikes a flint glass beat, the white light is separated into its component colors. Which of the following statements contains a valid prediction of the relative indices of refraction for red and violet light and a justification of that prediction? a) Index of refraction of red light in flint glass is greater than that of violet light because red light refracts more inside the flint glass. b) Index of refraction of red light is less than violet because it refracts less. c) Index of refraction of violet light is greater than red because it refracts more d) Index of refraction of violet light is greater than red because it refracts less. 2. Relevant equations 3. The attempt at a solution 1. if you brought a positive charge to it, it would become positive and ground removes electrons, but as the grounding is removed and the object would it become net zero, or neutral? Or remain positively charged 2. I said b, because red refracts least right?
