A mass ' \(\mathrm{M}\) ' is moving with constant velocity parallel to \(\mathrm{X}\)-axis. Its angular momentum with respect to the origin is
- A constant
- B zero
- C decreasing
- D increasing
Answer & Solution
Correct Answer
(A) constant
Step-by-step Solution
Detailed explanation
Angular momentum with respect to origin:
\(\mathrm{L}=\mathrm{r} \times(\mathrm{mv})\)
The variables \(\mathrm{r}, \mathrm{m}\) and \(\mathrm{v}\) are constant so, \(\mathrm{L}=\) Constant
\(\mathrm{L}=\mathrm{r} \times(\mathrm{mv})\)
The variables \(\mathrm{r}, \mathrm{m}\) and \(\mathrm{v}\) are constant so, \(\mathrm{L}=\) Constant
