Ответы на вопросы:
How to calculate the electric field due to disk of charge?
We suppose that we have a circular disc of radius a bearing a surface charge density of ? coulombs per square metre, so that the total charge is Q=?a2?. We wish to calculate the field strength at a point P on the axis of the disc, at a distance x from the centre of the disc. 2??r?r4??0?x(r2+x2)3/2=?x2?0?r?r(r2+x2)3/2. 20 июн. 2021?г.
What is the electric field at the centre of a charged disc?
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.
How do you find the electric field of a charge?
E = F q test = k | Q | r 2 . E = F q test = k | Q | r 2 . This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.
What is the formula for the electric field in terms of charge?
The Electric field formula that gives its strength or the magnitude of electric field for a charge Q at distance r from the charge is E = k Q r 2 , where k is Coulomb's constant and the units of the electric field are Newtons/Coulomb.
