MCQ
Consider the following two equations:
$A. \overrightarrow{\text{R}}=\frac{1}{\text{M}}\sum\limits_{\text{i}}\text{m}_\text{i}\overrightarrow{\text{r}}_\text{i}$
$B. \overrightarrow{\text{a}}_\text{cm}=\frac{\overrightarrow{\text{F}}}{\text{M}}$
In a noninertial frame
$A. \overrightarrow{\text{R}}=\frac{1}{\text{M}}\sum\limits_{\text{i}}\text{m}_\text{i}\overrightarrow{\text{r}}_\text{i}$
$B. \overrightarrow{\text{a}}_\text{cm}=\frac{\overrightarrow{\text{F}}}{\text{M}}$
In a noninertial frame
- ABoth are correct.
- BBoth are wrong.
- ✓$A$ is correct but $B$ is wrong.
- D$B$ is correct but $A$ is wrong.
