Consider the reading on coulombs law and on vectors addition. how does the magnitude of the force on ball 1 in this case compare to the force on ball 1 in the previous question?

Force on ball 1 is lesser because the charge is now distributed over the length of the rod. A sketch of the problem can be found in the attachment below. The rod can be assumed to be a continuous distribution of particles that each divide the single charge q2 along the length of the rod. In order to understand this, analysis using the basic definition of columbs law is helpful.

Explanation:

First we divide the rod into infinitesimal segements, each of which has a point charge. Then we drive the expression for the force of interaction of that segement with the charge q1. Then, integrate over the length of the rod from -a to +a.

The detailed step by step solution can be found in the attachment below.

Thank you for reading this and I hope it is helpful to you.

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
