    Right-handed fermions in charged weak interactions

    I've heard that it's not possible for right-chiral fermions to participate in charged weak interactions (those involving a W boson). Is that really true? Wouldn't that mean that a right-chiral electron couldn't undergo electron capture? And that a right-chiral muon or tau couldn't even decay...

    Electric Field for the circular path of positively charged particle

    Here is picture. Answers is A. https://ibb.co/m6Bpb2V My attempt was that I thought if i were to place a positive test charge then it would go from top to bottom if there was a positive charge in the center it was avoiding and a positively charged particle at the top, but an...

    Question about charged circular dish-an old topic

    A circular dish is charged with an iron rod in the center. When the dish rotates, someone on the ground considers that there is current and generates magnetism and the iron rod becomes a magnet; while someone else standing on the dish considers that there is no current and no magnetism generated...

    postion vs time graph for moving charged particle?

    Question {Consider the system shown to the right. Particles 1 and 2 are fixed in place while particle three is placed at the location shown and released. Let’s look at the mechanics of q3, which has a mass of 3.00 X 10-5 kg. What will be the net force on q3? What will be q3’s acceleration...

    Charged or discharged

    Dear all, I have an amusing experiment with my smart phone charger. That is, after charging it fully, I connect its input and output toghether, and get surprise result. Could you see in my youtube clip and give your explanation here -XtVLUv4pgg Thanks Thinh Nghiem

    electric field of a charged disc on an axial point.

    I need to find the electric field of a uniformly charged disc at a point on its axis through the centre. At first I calculated the potential Φ. Φ=(σ/2ε0)[( a^2 + x^2)^(1/2) - |x| ] where a is the radius of disc, x the distance of axial point from centre of the disc and σ the charge density...

    Potential of Non-Uniformly Charged Spherical Shell

    A thin spherical shell of radius R carries a surface charge density of the form kcos^3 θ . Find the electric field inside and outside the sphere and demonstrate explicitly that its components satisfy the relevant boundary conditions at the surface. So, I can work this all the way to...

    Force acting on charged parabola

    So I have an interesting problem that I've been thinking about. First off, it is not a homework problem. This is a possible solution to a problem I am working on in my lab. If I have a hemisphere made out of a metalized material with a charge Q uniformly distributed on it, what will the force...

    Charged Teflon Rod & Aluminum (Conductor vs Insulator type question)

    Hello, Just wanted to check my some of my reasoning to these. If anyone could confirm if these answer I got are right (or point me in the right direction if they aren't!) I'd really appreciate that. Thanks! Question Suppose a student rubbed a Teflon rod with wool then briefly touched it...

    magnet deflecting charged particles, logical, but fictional problem.

    An alien civilization has crossed the galaxy to invade the Earth and enslave humanity, again. Their attacks have been successful so far because their assault troops are equipped with handheld weapons that project beams of charged particles (protons & electrons) at very high speeds, able to...

    magnetic moment of charged particles

    im having difficulty understanding how physicists measure the magnetic moment of charged particles. Some articles i have read state that a charged particle will turn in an external magnetic field so that its magnetic poles align with the opposite poles of the external magnetic field. But, other...

    acceleration of electron in between charged plates

    dear.if the x-component and y-component of velocity is given i.e Vx &Vy.and E (electric field) is also given. then what equation should i use to find acceleration of the electron. i only know about E=F/e(relation of electric field and force) F=ma.if i want to find the "acceleration" if Vx ,Vy...

    Need help with Proper integral of a uniformly charged rod

    A uniformly charged rod is places along the x-axis from x=0 to x= L. carefully set up, but do not solve the proper integral to determine the x component of the electric field at the point (L,a) i know for a line dq=λdl i think its something along the lines of Ey=Kλy= \int...
