Calcul de flux d’un champ vectoriel | Théorème de Gauss–Ostrogradski- EXERCICE CORRIGÉ 🧠

A solved exercise on verifying the Gauss-Ostrogradsky theorem in spherical coordinates. It calculates the flux of a spherically symmetric vector field through a closed surface and verifies the relationship between divergence and flux. A fundamental exercise for understanding field theory and integral theorems!
