A particle performs `SHM` of time period `T` , along a straight line. Find the minimum time interval to go from position `A` to position `B`. At `A` both potential energy and kinetic energy are same and at `B` the speed is half of the maximum speed. |

Answer» Correct Answer - `(T)/(24)` `x_(A)=(A)/(sqrt(2))` and for `x_(B),(omegaA)/(2)=omegasqrt(A^(2)-x_(B)^(2))` or `x_(B)=(sqrt(3))/(2)A` or `omega t_(A)=(pi)/(4)` and `omega t_(B)=(pi)/(3)` or `omega (t_(B)-t_(A))=(pi)/(3)-(pi)/(4)` or`(pi)/(3)-(pi)/(4)=(2pi)/(T)t` or `t=(T)/(2pi)xx(pi)/(12)=(T)/(24)` `Ans. (T)/(24)` |
