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}} $$ = 2\pi \sqrt {\frac{1}{g}} $= $2\ sec$
$T = 2\pi \sqrt {\frac{{2R}}{g}} $$ = 2\pi \sqrt {\frac{1}{g}} $= $2\ sec$
[As diameter $2R = 1$ $meter$ given]
