Two bar magnets A and B are placed one over the other and are allowed to vibrate in a vibration manetometer. They of A and B are on the same side, while opposite poles lie on the same side. If M_(A) and M_(B) are the magnetic moments of A and B and if M_(A)gtM_(B), the ratio of M_(A) and M_(B) is |

Answer» `4:3` `n=(1)/(2pi)sqrt((MB_(H))/(I)` `(n_(1))/(n_(2))=sqrt((M_(A)+M_(B))/(M_(A-M_(B))` `n_(1)=20, n_(2)=15` (GIVEN) `20/15=sqrt((M_(A)+M_(B))/(M_(A-M_(B))` `implies(M_(A)+M_(B))/(M_(A)-M_(B))=(4/3)^(2)` `implies9[M_(A)+M_(B)]=16[M_(A)-M_(B)]` `implies7 M_(A)=25 M_(B)` `M_(A):M_(B)=25:7` |
