MCQ
A ring whose diameter is $1\ meter$, oscillates simple harmonically in a vertical plane about a nail fixed at its circumference. The time period will be ....... $\sec$.
  • A
    $1/4$
  • B
    $1/2$
  • C
    $1$
  • ✓
     $2$
✓

Answer

Correct option: D.
 $2$
d
$T = 2\pi \sqrt {\frac{{2R}}{g}} $$ = 2\pi \sqrt {\frac{1}{g}} $= $2\ sec$             

[As diameter $2R = 1$ $meter$ given]
