Two small spheres each having the charge \[+Q\] are suspended by insulating threads of length \[L\] from a hook. This arrangement is taken in space where there is no gravitational effect, then the angle between the two suspensions and the tension in each will be [IIT 1986] |
| 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. | \[{{180}^{o}},\,\frac{1}{4\pi {{\varepsilon }_{0}}}\frac{{{Q}^{2}}}{2{{L}^{2}}}\] |
