Electric fields originate from electric charges, or from time-varying magnetic fields.

The electric field is represented by the imaginary lines of force. For the positive charge, the line of force come out of the charge and for The constant field is obtained by placing the two conductor parallel to each other, and the potential difference between them remains same at every point.The strength of an electric field E at any point is defined as the electric force F exerted per unit positive Additionally, field strength varies as the inverse square of the distance between the charge and That depends on the strength of the electric field, and on the length of time the electron has...Now, instead of solving for the electric field strength, let's solve for the change in the potential between two positions, a and b, in an electric field. Note in this expression that we are starting at a and going to b. The integral notation is read as "the negative integral from a to b of E dr." Point Charges.We have learnt that objects that carry charge feel forces from all other charged objects. It is useful to determine what the effect of a charge would be at every point surrounding it. To do this we need some sort of reference.

Since the electric field is the electric force per unit charge, the electric field lines are sometimes called lines of force. The pattern of electric field lines also provides information about the magnitude or strength of the field. Notice in Figures 18.23 and 18.24 that near the charges, where the electric...Опубликовано: 20 янв. 2013 г. A short video explaining what electric field strength is.This is aimed at A level, I am a maths tutor and physics tutor based in the UK http This is what happens when you reply to spam email | James Veitch - Продолжительность: 9:49 TED Recommended for you.A charged object in an electric field experiences a force due to the field. The electric field strength, E, at a point in the field is defined as the force per unit charge on a positive test charge placed at that point.Two 10-cm-diameter charged disks face each other, 20 cm apart. Both disks are charged to + 50 nC. What is the electric field strength at (a) the midpoint between the two disks and (b) a point on the axis 5.0 cm from one disk?What is the electric field strength between the disks. A proton is shot from the negative disk toward the positive disk. Where Q is the charge of the disks, A is the area of the disks and e_0 is the vacuum permisivity equal to 8.85*10^-12 C^2/Nm^2

a) E=Q/(ε₀*A), where A=(πD^2)/4 ==>

E=4Q/ (πε₀D^2)=4*11e-9/(π*8.854e-12*0.04^2)

E=988652 V/m

b) e=1.6e-19 proton price, m=1.6726e-27 proton mass, d=0.0015 m

0.5mv^2=eU, where U=dE ==>

v=√(2edE/m)=
