Shred a paper in tiny pieces. Take a comb and comb your hair. Now bring the comb closer to the paper pieces. What will you observe?

A The paper pieces will get repelled due to magnetic force.
B The paper pieces will get repelled due to electrostatic force.
C The paper pieces will get attracted and stick to the comb due to electrostatic force.
D The pieces will get attracted and stick to the comb due to frictional force.


Ans 1:

Class : Class 8
The correct ans is option C because electrostatic force is a non contact force which is similar to magnetic force and the comb is like a magnet and tin pieces of paper are like the metal here (So the comb will attract the tiny pieces of paper).
