Assertion: Time period of vibration of a pair of magnets in sum position is always smaller than in difference position. Reason:`T=2pi sqrt(I//MH), where symbols have their standard meaning.A. If both Assertain and Reason are true and Reason is the correct explanation of AssertainB. If both Assertain and Reason are true but Reason is not correct explantion of AssertainC. If Assertion is true but Reason is falseD. If Assertion is false but Reason in true. |

Answer» Correct Answer - B The time period in sum position, `T_(s)=2pi sqrt((I_(s))/(M_(s)H))` `where, " "I_(s)+I_(1)+I_(2) and M_(s)=M_(1)+M_(2)` ` " " T_(s)=2pi sqrt((I_(1)+I_(2))/((M_(1)+M_(2))H))` Time period in difference position, ` " " T_(d)=2pi sqrt((I_(1)+I_(2))/((M_(1)-M_(2))H)) Rightarrow T_(s)lt T_(D)` |
