A combination of two magnets has a froquency of 16 ascillations oscillation//min. with dissimilar poles together Find the ratio of magnetic moments of magnets |
|
Answer» Solution :When SIMILAR poles are together, net MAGNETIC moment `=M_(1)-M_(2)` `f_(1)=1/2pi sqrt((M_(1)+M_(2))B/1)=16` When dissimilar poles together, net magnetic moment `=M_(1)-M_(2)` `f_(2)=1/2pi sqrt((M_(1)-M_(2))B/1)=12` Dividing (i) by (ii) we GET  `sqrt((M_1 + M_2)/(M_1-M_2))=(16)/(12)=4/3`On SOLVING we get`M_(1)/M_(2)=25/7`
