    Initially, sphere A has charge of-50 e and sphere B has a charge of +20e. The spheres are made of conducting material and are identical in size. If the spheres touch each other, what is the resulting charge on sphere A?

    A)  -15e                     

    B)  -30e 

    C)  +30e                    

    D)  +15e
