Materials and Components An atom of a rare gas is placed is an electric field E. Then The nucleus will be shifted in the direction of E by an amount which is proportional to E. The nucleus will be shifted in the direction of E by an amount which is independent of E. The nucleus will be shifted in a direction opposite to that of E. The nucleus will not be shifted. The nucleus will be shifted in the direction of E by an amount which is proportional to E. The nucleus will be shifted in the direction of E by an amount which is independent of E. The nucleus will be shifted in a direction opposite to that of E. The nucleus will not be shifted. ANSWER DOWNLOAD EXAMIANS APP
