MCQ
If body having initial velocity zero is moving with uniform acceleration $8\,\,m/{\sec ^2}$ the distance travelled by it in fifth second will be.........$metres$
- ✓$36$
- B$40$
- C$100$
- D$0$
✓
Answer
Correct option: A.
$36$
a
(a) Distance travelled in ${n^{th}}$ second $ = u + \frac{a}{2}(2n - 1)$
(a) Distance travelled in ${n^{th}}$ second $ = u + \frac{a}{2}(2n - 1)$
Distance travelled in ${5^{th}}$ second
$ = 0 + \frac{8}{2}\left( {2 \times 5 - 1} \right)$
$=36\,m$

A lamina is made by removing a small disc of diameter $2 \ R$ from a bigger disc of uniform mass density and radius $2 \ R$, as shown in the figure. The moment of inertia of this lamina about axes passing through $O$ and $P$ is $I _0$ and $I _{ p }$, respectively. Both these axes are perpendicular to the plane of the lamina. The ratio $\frac{ I _{ P }}{ I _0}$ to the nearest integer is:
