Why might a PC monitor be covered with dust?

After gaining electrons from the cloth, can the polythene rod attract small pieces of paper?

Answer:

  • The attractive forces between the dust particles and Television Screen is due to static electricity. The free dust particles have some residual charge due to force of friction from air or colliding dust particles while the television screen has an opposite charge. They attract and dust settles on it.
  • If a polythene rod is rubbed with cloth, the rod can lift small pieces of paper. This can be explained by stating that the rod becomes charged. A charged object will attract a neutral object until it touches and then it is repelled.
