A) \[-\,5.6\times {{10}^{-11}}N/C\]
B) \[-\,4.8\times {{10}^{-15}}N/C\]
C) \[-\,1.6\times {{10}^{-19}}N/C\]
D) \[-\,3.2\times {{10}^{-19}}N/C\]
Correct Answer: A
Solution :
[a] \[-eE=mg\] \[\vec{E}=-\frac{9.1\times {{10}^{-31}}\times 10}{1.6\times {{10}^{-19}}}=-5.6\times {{10}^{-11}}N/C\]You need to login to perform this action.
