A) \[9.2\times {{10}^{-4}}m\]
B) \[6.5\times {{10}^{-4}}m\]
C) \[6.5\times {{10}^{-5}}m\]
D) \[12.4\times {{10}^{-4}}m\]
Correct Answer: A
Solution :
[a] From the relation \[\frac{I}{O}=\frac{v}{u}\] Here, \[O=1.39\times {{10}^{9}},\] \[v=0.1\,m,\] \[u=1.5\times {{10}^{11}}m\] \[\therefore \] \[l=\frac{0.1}{1.5\times {{11}^{11}}}\times 1.39\times {{10}^{9}}\]\[=9.2\times {{10}^{-4}}m\]You need to login to perform this action.
