Two identical conducting spheres carry charges of `+5.0 mu C` and `-10 mu C`, respectively. The centers of the spheres are initially separated by a distance L. The two spheres are brought together so that they are in contact. The spheres are then returned to their original separation L. What is the ratio of the magnitude of the electric force on either sphere after the spheres are touched to that before they were touched ?

A

`(1)/(1)`

B

`(9)/(5)`

C

`(4)/(5)`
