Stress in Physics
Stress in Physics Stress in Physics The internal restoring force acting per unit area of cross–section of the deformed body is called stress. Stress = (Internal Restoring force/Area of cross section) = Finternal/A = Fexternal/A SI Unit : Nm–2 Dimensions : [M1 L–1 T–2] Types of stress (Stress in Physics) (a) Longitudinal Stress (b) Volume…
Form of Coulomb’s Law when Dielectric is filled partially between the charges
Form of Coulomb’s Law when Dielectric is filled partially between the charges Coulomb’s Law with partially filled Dielectric between the charges :- Suppose two charge particles q1 and q2 are placed r distance apart in vacuum, then from Coulomb’s Law force acting between them:- Now let a dielectric medium ( of permittivity εr…

Electrostatic Equilibrium of charged particles
Electrostatic Equilibrium of charged particles Electrostatic Equilibrium:- In equilibrium net electric force on every charged particle is zero. The equilibrium of a charged particle, under the action of Colombian forces alone can never be stable. Equilibrium is of three types:- (a) Stable Equilibrium : A charge is initially in equilibrium position and is displaced by…

Principle of superposition
Principle of superposition Principle of superposition :- The force is a two body interaction, i.e., electrical force between two point charges is independent of presence or absence of other charges and so the principle of superposition is valid, i.e., “force on a charged particle due to number of point charges is the resultant…
