MCQ

Two bodies have same mass and speed, then:

A
Their momentums are same.
B
The ratio of momentums is not determined.
C
The ratio of their magnitudes of momentum is one.
✓
Both $(B)$ and $(C)$ are correct.

✓

Answer

Correct option: D.

Both $(B)$ and $(C)$ are correct.

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.
