The Coulomb force between them is:A point charge of $5\ \mu$C is placed at the origin. The electric field magnitude at $0.5$ m is:A dipole consists of $+q$ and $-q$ separated by distance $d$. Its dipole moment direction is:A closed surface encloses a net charge of $4\ \mu$C. The total electric flux through the surface is:Coulomb's law gives the electrostatic force between two point charges as:SI unit of electric charge is the coulomb (C). 1 C is approximately:Electric field E at a point due to a point charge q at distance r is:Electric flux Φ through a closed surface enclosing total charge Q_enc (Gauss's law) equals:An infinite uniform line of linear charge density λ produces an electric field at perpendicular distance r equJust outside a large uniformly-charged conducting sheet with surface charge density σ, the magnitude of the elTwo equal point charges q each are placed at distance d. The electrostatic PE of the system (zero at infinity)Electric potential V due to a point charge q at distance r is:The electric field at the centre of a uniformly-charged thin spherical SHELL of radius R is:Torque on a dipole of moment p placed in a uniform field E at angle θ is:Two large parallel conducting plates carry equal and opposite surface charge density σ.
