By convention, we call one type of charge “positive”, and the other type “negative.” For example, when glass is rubbed with silk, the glass becomes positively charged and the silk negatively charged.

Complete step by step answer:irstly, when the comb is used to rub dry hair, it always acquires a negative charge or electron which the hair carries, where the comb is induced with the electron gotten from the hair then immediately the comb which is negatively charged comes in contact with the piece of paper which is …

Hair is a complex keratin fiber, which basically consists of three layers: the medulla, the cortex, and the cuticle. To understand the effect of hair care products, the surface charge of the hair has to be taken into closer consideration. Untreated human hair has a strongly negative surface charge.

In Figure 4a(i), the untreated hair predominantly has a surface charge value of around −15 mC/m2. Upon treatment with the hair conditioner, a positive shift in the surface charge is observed over most of the surface, with regions with charge densities of 20 mC/m2 present.

Precipitation static is an electrical charge on an airplane caused by flying through rain, snow, ice, or dust particles. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers.

Electric charge comes in two varieties, which we call positive and negative. Like charges repel each other, and unlike charges attract each other. Thus, two positive charges repel each other, as do two negative charges. A positive charge and a negative charge attract each other.

Electric Charge

• protons are positively charged.
• electrons are negatively charged.
• neutrons have zero charge.

Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together.

Touch the object to the electroscope knob and watch the foil closely. If the foil separates farther, the charge on the object is negative. If the foil comes back together, the charge is positive.

Sir Williams Gilbert

1. positive charge – having a deficiency of electrons; having a higher electric potential. electric charge, charge – the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; “the battery needed a fresh charge”

When two negatively charged objects are brought near each other, a repulsive force is produced. When two positively charged objects are brought near each other, a similar repulsive force is produced. When a negatively charged object is brought near a positively charged object, an attractive force is produced.

Induction charging is a method used to charge an object without actually touching the object to any other charged object. An understanding of charging by induction requires an understanding of the nature of a conductor and an understanding of the polarization process.
