... electrical charges are not created. Instead, both objects contain both positive and negative charges. During the rubbing process, the negative charge is transferred from one object to the other leaving one object with an excess of positive charge and the other with an excess of negative charge. The ...

... Apparently they are lifted to a region where their horizontal drift velocity is less (namely, above the peak in drift velocity near 100 km, cf. Fig. 2). However, when the wind is polewards electrons will be depressed into lower regions where their effect on absorption is increased yet the bulk of th ...

Properties of Electric Charges
... • The direction of the force is always along a line joining the 2 charges – Forces are attractive or repulsive depending on the sign (+ or –) of the charges involved Coulomb's Law – In agreement with Newton’s 3rd Law: Force on one charge is equal in magnitude but opposite in direction to force on ot ...
