WebElectric field due to a charged disc sets up an electric field around it. You need to imagine the disc as a collection of rings to derive the formula. Are yo... WebMar 24, 2024 · The electric field at the centre of the disc is zero. Reason : Disc can be supposed to be made up of many rings. Also electric field at the centre of uniformly charged ring is zero. Answer (a) The electric field due to disc is superposition of electric field due to its constituent ring as given in Reason. Q.19.
Calculating the electric field of a disk - Mathematics Stack Exchange
WebJan 19, 2010 · 372. 2. f2009049 said: The electric filed at a distance x from the center of a uniformly charged disc of radius R,along the axis passing through the center is given by E = sigma/2e (1-x/rt (x^2+R^2)) where sigma is surface charge density and e is permittivity of free space .Putting x=0 in this eqn gives filed at the center of the disc =sigma/2e ... WebThe ring potential can then be used as a charge element to calculate the potential of a charged disc. Since the potential is a scalar quantity, and since each element of the ring is the same distance r from the point P, the potential is simply given by. If the charge is characterized by an area density and the ring by an incremental width dR ... fewo handrick l25
