A) \[\overrightarrow{F}.\overrightarrow{\tau }=0\]
B) \[\overrightarrow{r}.\overrightarrow{\tau }>0\]
C) \[\overrightarrow{F}.\overrightarrow{\tau }<0\]
D) \[-\hat{i}+\hat{j}+\hat{k}\]
Correct Answer: B
Solution :
The position vector of centre of mass \[a=1,b=1,c=-2\] \[a=0,b=-1,c=-2\] \[_{Z}^{A}Z\xrightarrow[{}]{{}}{{\,}_{Z+}}_{1}^{4}Y\xrightarrow[{}]{{}}\,_{Z-1}^{A-4}{{B}^{*}}\xrightarrow[{}]{{}}\,_{Z-1}^{A-4}B,\] \[\beta ,\alpha ,\gamma \] The centre of mass changes its position only under the translatory motion. There is no effect of rotatory motion on centre of mass of the body.You need to login to perform this action.
