Question

What do you understand by static or frictional electricity?
A. Discharging of two bodies on rubbing them together is called static or frictional electricity.
B. Charging of two bodies on rubbing them together is called static or frictional electricity
C. Electricity which is static is called static or frictional electricity.
D. Electricity on high friction bodies is called static or frictional electricity.

Answer 1

Hint: Substance which gains electric charges on rubbing with a suitable substance is known as an electrified or charged substance. These currents are generally very small in magnitude.

Complete step-by-step answer:
Static or frictional electricity is a type of electricity that is produced whenever any two suitable substances like hair and comb, glass rod and silk, sealing wax, and wool are rubbed together vigorously over each other to develop a charge which is small in magnitude. It is also known as triboelectricity.
Therefore option B is the correct option, that is Charging two bodies on rubbing them together is called static or frictional electricity

So, the correct answer is “Option B”.

Additional Information:
Few uses of static electricity include painting, Xerox machines, and pollution control. In Xerox machines or printers the ink is attracted by the static electric charges. Static electricity has a property of attracting small dust particles towards itself thus it is used to control pollution.

The lightning that is caused during storms is a type of static electricity, it is also an example where static electricity is in a huge magnitude and can cause severe damage to death.
Remember that like charges repel and unlike charges attract each other.
Thus the charge produced by the electrostatic force is an unlike charge as compared to hair or paper bits so it attracts human hair or paper bits.

Note: Electric shocks can also be caused by Electrostatic discharge. The discharge of electrons from objects that are charged can happen more easily if the air surrounding the substance is dry.
