to answer this questions pay ur attention towards the properties of charges

1. like charges repel & unlike charges attract each other

2. electrostatic induction -

                                transfer of electrons takes place

      ~each charged body attract light uncharged body.

      ~each conducting body posses free electrons.

      ~bodies may be charged permanently by electrostatic induction too.

 

  Even an electrically neutral body can attrract a charged body as the body becomes deficient in eletrons or exess of electrons when it attracts +vely or -vely charged body respectively.
