A) \[4\times {{10}^{-10}}\]
B) \[4\times {{10}^{-11}}\]
C) \[4\times {{10}^{-12}}\]
D) \[4\times {{10}^{-13}}\]
Correct Answer: B
Solution :
Electric dipole moment = charge \[\times \] distance between positive and negative charge or \[p=q\times l\] \[\therefore \] \[6.4\times {{10}^{-30}}=1.6\times {{10}^{-19}}\times l\] \[\Rightarrow \] \[l=4\times {{10}^{-11}}m\]You need to login to perform this action.
