1.	Comment on the intensity of charge of an electric field when HF and dry air are placed between two charged parallel plates.
Answer» Solution :When a polar molecule like HF is placed between charged parallel PLATES, the molecule orients in such a way that the positive end of the molecule is DIRECTED towards the negatively charged plate and the negative end of the molecule is directed towards the positively charged plate. As a result of this, the intensity of the CHARGE on each plate is DIMINISHED. HOWEVER, when dry air (nitrogen, oxygen), which is non-polar in nature is placed, there would be no change in the intensity of the charge.
