A positively charged rod is brought close to one end of a neutral metallic plate as seen below. What type of charge is induced on the right side of the plate?

A. Positive

B. Negative

C. Neutral

D. Mixed charges

Answer;

A. Positive

Explanation; When a rod with positive charge is placed near a neutral piece of metal, positive charges in the metal are repelled by the positive charge on the rod. The negative electrons move towards the positively charged rod. The metal now has more negative charge at the end near the rod and more positive charge at the end away from the rod. The positively charged rod attracts the nearer negative charge more strongly than it repels the farther positive charge and an attractive force results.
