    Write the following steps in sequence that explain the phenomenon of redistribution of charges in an uncharged body in presence of a charged body. (A) As a result, at one end of the neutral body there is an excess of negatively charged particles and the other end there is an excess of positively charged particles. (B) Place a positively charged body near a neutral body. (C) The negatively and positively charged particles in the neutral body get attracted and repelled by the positively charged body.
