A) \[Q=(-2\sqrt{2)}\,q\]
B) \[Q=-\frac{q}{2}\]
C) \[Q=(2\sqrt{2)}\,q\]
D) \[Q=-\frac{q}{2}\]
Correct Answer: D
Solution :
Three forces\[{{F}_{41}},{{F}_{42}}\]and\[{{F}_{43}}\]are acting on Q as shown resultant of\[{{F}_{41}}\]and \[{{F}_{43}}=\sqrt{2}{{F}_{each}}\] \[=\sqrt{2}\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{Qq}{{{d}^{2}}}\]You need to login to perform this action.
