electromagnetism - Is there is any difference between Electric Flux (Psi) and Total number of Electric Field lines (EtimesArea)?


Is there is any difference between Electric Flux (Ψ) and Total number of Electric Field lines (E×Area)?


ψ=ΣQ, and ϕ = Electric field intensity × Area



where Area = Total surface integral over Gaussian surface

classical mechanics - Moment of a force about a given axis (Torque) - Scalar or vectorial?

I am studying Statics and saw that: The moment of a force about a given axis (or Torque) is defined by the equation: $M_X = (\vec r \times \...
