A) \[f\propto {{Z}^{2}}\]
B) \[+\sigma \]
C) \[-\sigma \]
D) zero
Correct Answer: B
Solution :
The product of force and time interval is called impulse. Also from Newtons second law, we have \[\Rightarrow \] \[f\propto {{Z}^{2}}\] The force on charge q due to electric field is \[+\sigma \]. \[-\sigma \] Impulse \[E=E+E=2E\]You need to login to perform this action.
