Electric flux in physics with problems and solutions

What is Electric Flux? “Total number of field lines passing through a certain element of area is called flux”. It may also be defined as “The scalar product of electric field intensity E and vector area  A“. Electric flux dimensional  formula It is denoted by Greek letter Φ. Φ=E.A Φ=EAcosθ Where θ is the angle between E and A.Electric flux is a scalar ...

coulomb’s law formula with examples and problems

Coulomb’s law definition “Coulomb’s law states that  force of attraction or repulsion between two electric charges is directly proportional to their magnitudes and inversely proportional  to the square of distance between them”.It is mathematically explained as: Charles Agustin Coulomb (1736-1806) measured electrical attractions and repulsions  quantitatively and deduced the law that governs them.His apparatus,shown in fig. This figure resembles the ...
