MCQ
Two rings of radii 1 meter and 5 meter start rolling simultaneously on an inclined plane without slipping. Which ring will reach the earth's surface first?
- ABig ring
- BSmall ring
- ✓Both together
- DNothing can be said
✓
Answer
Correct option: C.
Both together
C
We know that the time taken to reach the earth's surface (K2/R2) depends on. The value of I for a ring is 1. Therefore both the rings will reach the earth's surface simultaneously
