Two identical conducting spheres, fixed in space, attract each other with an electrostatic force of `0.108 N` when separated by `50.0 cm`, centre-to-centre. A thin conducting wire then connects the spheres. When the wire is removed, the spheres repel each other with an electrostatic force of `0.0360 N`. What were the initial charges on the spheres?

Options

A. `+-5xx10^(-6)C" and "+-15xx10^(-6)C`
B. `+-1.0xx10^(-6)C" and "+-3.0xx10^(-6)C`
C. `+-2.0xx10^(-6)C" and "+-6.0xx10^(-6)C`
D. `+-0.5xx10^(-6)C" and "+-1.5xx10^(-6)C`

Answer

B
