Hey Aïcha🥰😍💝🌹👑🕋, good to see you again. Here's the solution for Exercise 9: EXERCICE 9: champ créé par un disque chargé 1) Détermination du champ créé au point M de l'axe (Oz) pour un disque de rayon R. Step 1: Consider an infinitesimal ring of radius r and thickness dr on the disk. The charge on this ring is dq = (2 r dr). The electric field dE created by this ring at a point M on the z-axis at coordinate z has only a component along the z-axis due to symmetry. The magnitude of this component is given by:
