Magnets `A` and `B` are geometrically similar but the magnetic moment of `A` is twice that of `B`. If `T_(1)` and `T_(2)` be the time periods of the oscillation when their like poles and unlike poles are kept togather respectively, then `T_(1)/T_(2)` will beA. `1/3`B. `1/2`C. `1/sqrt(3)`D. `sqrt(3)` |

Answer» Correct Answer - C `T_(Sum)=2pisqrt(((I_(1)+I_(2)))/((M_(1)+M_(2))B_(H)))` `T_(d i ff)=2pisqrt(((I_(1)+I_(2)))/((M_(1)+M_(2))B_(H)))` `implies T_(s)/T_(d)=T_(1)/T_(2)=sqrt((M_(1)-M_(2))/(M_(1)+M_(2)))=sqrt((2M-M)/(2M+M))=1/sqrt(3)` |
