1.	in an experiment it was found that string vibrates in n loops when a mass M is placed on the pan. What mass should be placed on the pan to make it vibrate in 2n loops with same frequency ? ( neglect the mass of pan )A. `M//4`B. 4 MC. 2 MD. `M//2`
Answer» Correct Answer - b As the string vibrates in n loops therefore, `l=(nlambda)/2` therefore, v would become `1/2` time. As `v prop sqrt(T)` Threrfore to make v half- time T must be made `1/4` time i.e. M/4.
