two small charged spheres having charges of 2 × 10−7 C and 3 × 10−7 C placed 30 cm apart in air? Answer Repulsive force of magnitude 6 × 10−3 N Charge on the first sphere‚ q1 = 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

Kelvin dropper Theory A normal uncharged piece of matter has equal numbers of positive and negative electric charges in each part of it‚ located close together‚ so no part of it has a net electric charge. The positive charges are the atoms’ nuclei which are bound into the structure of matter and are not free to move. The negative charges are the atoms’ electrons. In electrically conductive objects such as metals‚ some of the electrons are able to move freely about in the object. When a charged

The Progress of the Atomic structure Different theories about the atomic structure were introduced over time. These theories changed as a result of development of different experiments. Leucippus was the first to introduce the theory of atomism‚ however he didn’t write about his theories in detail. However‚ Democritus‚ his student wrote about the theory of atoms in detail. He theorised that everything was composed of atoms and that atoms are solid and indestructible. He also had a theory that

Electric Field and the Movement of Charge Perhaps one of the most useful yet taken-for-granted accomplishments of the recent centuries is the development of electric circuits. The flow of charge through wires allows us to cook our food‚ light our homes‚ air-condition our work and living space‚ entertain us with movies and music and even allows us to drive to work or school safely. In this unit of The Physics Classroom‚ we will explore the reasons for why charge flows through wires of electric circuits

Static electricity is the buildup of electrical charges on the surface of some object or material. Static electricity is usually created when materials are pulled apart or rubbed together‚ causing positive (+) charges to collect on one material and negative (−) charges on the other surface. Results from static electricity may be sparks‚ shocks or materials clinging together. Static electricity is the accumulation of electrical charges on the surface of a material‚ usually an insulator or non-conductor

Field • An electrostatic field is a phenomenon that is very similar to a magnetic field. When an object is electrically charged‚ it creates an electrostatic field. If an object has an excess of electrons‚ then it’s considered to have a negative charge. If an object has fewer electrons than its surrounding environment‚ though‚ it’s considered to be positively charged. Just like with magnetic fields‚ two objects that are oppositely charged will attract each other. This scientific truth is the core
