Give reason: 'Small and light pieces of paper are attracted by a comb run through dry hair.'

(N/A) When a comb is run through dry hair,it acquires an electric charge due to friction. The pieces of paper are initially neutral. When the charged comb is brought near the paper,it induces a redistribution of charges in the paper,a process called electrostatic induction. This creates a dipole moment in the paper. Since the electric field produced by the comb is non-uniform,the force on the induced charges is not balanced,resulting in a net attractive force towards the comb.
