A) \[{{\left( \frac{2}{3} \right)}^{1/2}}\]
B) \[2/3\]
C) \[4/9\]
D) none of the above
Correct Answer: C
Solution :
Dimension intensity \[\propto \] (distance)2 \[I\propto {{d}^{2}}\] Hence \[\frac{{{I}_{1}}}{{{I}_{2}}}={{\left( \frac{{{d}_{1}}}{{{d}_{2}}} \right)}^{2}}={{\left( \frac{20}{30} \right)}^{2}}=\frac{4}{9}\] Hence, \[{{I}_{1}}:{{I}_{2}}=4:9\]You need to login to perform this action.
