MCQ
As per given figure to complete the circular loop what should be the radius if initial height is $5 \,m$ .......... $m$.
- A$4$
- B$3 $
- C$2.5$
- ✓$2$
✓
Answer
Correct option: D.
$2$
d
(d) $h = \frac{5}{2}r$ $⇒$ $r = \frac{2}{5} \times h = \frac{2}{5} \times 5 = 2\,metre$
(d) $h = \frac{5}{2}r$ $⇒$ $r = \frac{2}{5} \times h = \frac{2}{5} \times 5 = 2\,metre$
