Since comb accumulate negative charge therefore the hair must
have loose electron
and become positive charge. Therefore comb will attrac the
hair.
Hence correct option is A.
Add Answer to:
1) A plastic comb is pulled through initially neutral hair. The comb accumulates 1 μC of...

A long insulating rod suspended by insulating wires.Assume that the rod is initially electrically neutral. Forconvenience, we will refer to the left end of the rod as end A, andthe right end of the rod as end B . In the answer options for thisproblem, "weakly attracted/repelled" means "attracted/repelled witha force of magnitude similar to that which would exist between twoballs, one of which is charged, and the other acquires a smallinduced charge". An attractive/repulsive force greater than thisshould be...

1) A negatively charged Teflon (plastic) rod is held near two initially neutral aluminum pie plates that are touching as shown at right. The plates are held using insulating cups. The Teflon rod never touched the pie plates, and no sparks have jumped. Negatively charged Teflon rod a. Is the magnitude of the net charge of the small pie plate greater than, less than, or equal to the magnitude of the net charge of the large pie plate? If the...

(Figure 1) Consider three plastic balls (A, B, and C), each
carrying a uniformly distributed charge equal to either +Q, -Q or
zero, and an uncharged (neutral) copper ball (D). A positive test
charge (T) experiences the forces shown in the figure when brought
very near to the individual balls. The test charge T is strongly
attracted to A, strongly repelled from B, weakly attracted to C,
and strongly attracted to D.
What is the nature of the force between...

An electric field can induce an electric dipole in a neutral molecule (or atom) by pushing the positive and negative charges inside the molecule in opposite directions. The dipole moment of the induced dipole is directly proportional to the electric field at the molecule. That is, p⃗ =αE⃗ , where p⃗ is the induced dipole moment, α is called the polarizability of the molecule, and E⃗ is the electric field at the molecule. A stronger electric field at the molecule results in a...
