Question

5) If the electric field between the plates of a given air-filled capacitor is weakened by removing charge from the plates, the capacitance of that capacitor A) increases. B) decreases. C) does not change. D) It cannot be determined from the information given 6) Which set of equipotential surfaces matches this electric field? o V 50 V 0 V 50 V oV 50 V 50 V 7) A laser beam passing from medium 1 to medium 2 is refracted as shown. Which is true? A)n, n C) There's not enough information to compare n, and n 8) A hydrogen nucleus, which has a charge +e, is situated to the left of a carbon nucleus, which has a charge +6e. Which statement is true? A) The electrical force experienced by the hydrogen nucleus is to the left, and the magnitude is equal to the force exerted on the carbon nucleus. B) The electrical force experienced by the hydrogen nucleus is to the left, and the magnitude is greater than the force exerted on the carbon nucleus C) The electrical force experienced by the hydrogen nucleus is to the left, and the magnitude is less than the force exerted on the carbon nucleus.

Explanation / Answer

5) C) does not change

6) Option C) is correct

7) B)   n1 > n2   (In medium 2 beam bends away from the normal)

8) A) The electrical force experienced by the hydrogen nucleus is to the left, and the magnitude is equal to the force exerted on the carbon nucleus.
