Answer:
Step-by-step explanation:
When negatively charged rubber rod is brought close to sphere X it induces positive charge on sphere and simultaneously negative charges is induced in the sphere opposite to the side of rod .
At the same time Sphere Y is touched to the sphere X , this causes the negative charge to shift to the sphere Y with the help of negative charged rod which repels the electrons to sphere Y.
When rubber rod is moved far away from X and Y then final charge possessed by X and Y spheres are
X:Positively charge
Y:Negatively charge
