    PHYSICS ESSAY HOW ELECTROSTATICS INFLUENCE OUR LIVES? INTRODUCTION We all are familiar with the term electricity which comes from batteries and which is used to light bulbs‚ buzzers‚ and other electrical devices. We also know that conductors are those objects which conduct electricity easily and insulators do not conduct electricity at all. This is basic knowledge but right now we are going into detail about electricity and static electricity. ELECTROSTATICS Many of us have this wrong concept

    Electrostatics Electrostatics is a part of physics is that the study and analysis of electricity‚ its properties and its applications. Electrostatics was discovered when an ancient Greek philosopher named Thales. In 600 B.C.‚ Thales learned that when he rubbed amber with fur‚ it would start to attract other lightweight objects such as feathers and dust which is now known as a process called triboelectrification. This is also how we got the word electricity‚ which comes from the Greek word‚ elektron

    Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

    reached electrostatic equilibrium share a variety of unusual characteristics. One characteristic of a conductor at electrostatic equilibrium is that the electric field anywhere beneath the surface of a charged conductor is zero. If an electric field did exist beneath the surface of a conductor (and inside of it)‚ then the electric field would exert a force on all electrons that were present there. This net force would begin to accelerate and move these electrons. But objects at electrostatic equilibrium

    What is Anti Static Wrist Band/Strap? An antistatic wrist strap is used to safely ground a person working on very sensitive electronic equipment‚ to prevent the buildup of static electricity on their body‚ which can result in electrostatic discharge. It is used in the electronics industry by workers working on electronic devices which can be damaged by ESD‚ and also sometimes by people working around explosives‚ to prevent electric sparks which could set off an explosion. It consists of a stretchy

    2 × 10−7 C Charge on the second sphere‚ q2 = 3 × 10−7 C econd Distance between the spheres‚ r = 30 cm = 0.3 m Electrostatic force between the spheres is given by the relation‚ Where‚ ∈0 = Permittivity of free space Hence‚ force between the two small charged spheres is 6 × 10−3 N. The charges are of same nature. Hence‚ force between them will be repulsive. Question 1.2: The electrostatic force on a small sphere of charge 0.4 μC due to another small sphere of between charge − 0.8 μC in air is 0.2
