ELECTROSTATICS exercise # 1 Question based on coulomb’s law 1 An electron at rest has a charge of 1.6 × 10–19 C. It starts moving with a velocity v = c/2, where c is the speed of light, then the new charge on it is – (1) 1.6 × 10–19 Coulomb (2) 1.6 × 10–19 …
This principle states that if a number of forces are acting on a single charged particle then the total force on the given charge is the vector sum of all the forces exerted on it by other charges.
Coulomb’s Law – Force between two point electric charges: The electrostatic force of interaction (attraction or repulsion) between two point electric charges is directly proportional to the product of the charges, inversely proportional to the square of the distance between them and acts along the line joining the two charges. Strictly speaking, Coulomb’s law applies …
3. Electrostatic induction If a charged body is brought near a neutral body, the charged body will attract opposite charge and repel similar charge present in the neutral body. As a result of this one side of the neutral body becomes negative while the other positive, this process is called ‘electrostatic induction’.
Charge is a scalar Quantity. Charge is conserved. Charge can not exist without of mass. Charge can not exist without mass though mass can exist without charge. Charge is transferable. If a charged body is put in contact with an another body, then charge can be transfered to another body. Charge is always associated with …
in this branch of science we can study about rest charge. If charge at rest it give five property Electric field, Force, potential, capacitance, and potential energy.
