A) \[\sqrt{3}\,\,N/C\]
B) \[4\,\,N/C\]
C) \[5\,\,N/C\]
D) \[20\,\,N/C\]
Correct Answer: D
Solution :
As, \[\omega =F\,\,ds\,\,\cos \theta \] \[=q\varepsilon ds\,\,\cos \theta \] \[4=0.2\varepsilon \times 2\cos \,{{60}^{o}}\] \[\Rightarrow \] \[\varepsilon =20\,N/C\]You need to login to perform this action.
