MCQ
Two bodies have same mass and speed, then:
- ATheir momentums are same.
- BThe ratio of momentums is not determined.
- CThe ratio of their magnitudes of momentum is one.
- DBoth (B) and (C) are correct.
✓
Answer
- Both (B) and (C) are correct.
Explanation:
Given that the mass and speed of two bodies are same.
We know that momentum is equal to p = mv.
But the momentums of two bodies are not equal, because momentum is a vector quantity.
The ratio of momentums is not defined because it is a vector quantity and ratio is a scalar quantity.
