Nuclear Forces

We already know about gravitational and electrostatic forces now a question arises that does these forces still hold when we talk about nuclear dimensions as gravitational force between two protons is far too less to hold them and electrostatic force between two protons always a force repulsive in nature . So what hold protons together to form a nucleus.


Fictitous Force and Free falling Elevator

A non inertial Frame of Refrence is the frame of refrence which is having acceleration a. Example Free Falling elevator
Newtons law are valid in inertial frame of refrence only. We cannot apply them as it is in non inertial frame of refrence as it left out the acceleration of the object because of the frame of refrence.
Let me provide simple example to illustrate this.

Physics books for CSIR-NET/JRF and GATE

Here are the list of Physics books for CSIR-NET/JRF and GATE which will be very helpful. It is hard for a person to collect these many books so i would advise you to go through these books while doing your masters in physics and make yourself appropriate notes for further reference and study. Classical mechanics   1.      Classical Mechanics by Herbert Goldstein 2.      Classical mechanics by Gupta … Continue reading Physics books for CSIR-NET/JRF and GATE »


You all know physicsgoeasy is my blog and i had already given a good amount of notes on basic electrostatics in this blog so I did not intend to write further on basic electrostatics topics. For detailed basic notes on electristatics you can visit my website and links to my blog postes of electrostatic related material are given below.

Overview of electrostatics and electricity

Overview of electrostatics and electricity Electrostatics involves electric charges namely positive and negative charges, the forces between them which is known as electric force , the field that surrounds them, and their behavior in materials. Coulumb’s law is the simple relation that governs electrostatic interactions and the field around the charges is described using the concept of electric field. Coulumb’s law is a inverse square … Continue reading Overview of electrostatics and electricity »
