I have these equations in my book, but I don't know how I can use them in this problem
Electric field of a plane has surface electric density σ: E = σ/2εε₀
Ostrogradski - Gauss theorem: Φ₀ = integral DdS
Can someone help me :((
I've learned that moving charges produce magnetic fields which in turn affect other charges in motion. After seeing explanations that point to special relativity, I am kind of confused. Can **ALL** magnetic fields be accounted as some kind of electric field from a particular reference frame...
Homework Statement :- electric field vs position how to plot it[/B]
Homework Equations :- force per unit charge[/B]
The Attempt at a Solution :- i know option 1 and 2 can never be an answer to this question but still i am confused between 3 and 4 option and help me solve with proper equation[/B]
I have a non conducting sphere with a charge ρ=A/r per uni vollume A is constant. suppose there is a cavity in the centre and within a particle of charge q. i want to find the E inside the sphere in respect with r.
The Attempt at a Solution
for radius equal of the cavity i...
A conducting coil of radius R is outside a long solenoid with a cross section of radius r. What is the emf induced in the coil?
Most example problems of this type I think are solved based on Faraday’s Law. These examples do not use the distance from the solenoid to the...
