A) \[{{180}^{o}},\,\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{Q}^{2}}}{{{(2L)}^{2}}}\]
B) \[{{90}^{o}},\,\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{Q}^{2}}}{{{L}^{2}}}\]
C) \[{{180}^{o}},\,\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{Q}^{2}}}{2{{L}^{2}}}\]
D) \[{{180}^{o}},\,\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{Q}^{2}}}{{{L}^{2}}}\]
Correct Answer: A
Solution :
(a) The position of the balls in the satellite will become as shown below Thus angle q = 180° and Force \[=\frac{1}{4\pi {{\varepsilon }_{0}}}\cdot \frac{{{Q}^{2}}}{{{(2L)}^{2}}}\]You need to login to perform this action.
