Two 10 cm diameter charged disks face each other, 20 cm apart. The left disk is charged to - 50 nC and the right disk is charged to + 50 nC.

Two 10 cm diameter charged disks face each other, 20 cm apart. The left disk is charged to - 50 nC and the right disk is charged to + 50 nC.A.) What is the electric field, both magnitude and direction, at the midpoint between the two disks?C.) What is the force on a -1.0 charge placed at the midpoint? (Is this just F=E*q?)

Let us find the electric field due to a charged disc ( q ) of radius R , at an axial distance of x .Taking a ring of radius r and width dr on the surface of the disc,Charge on the ring,q2qrdr...
