## Mathematics revision sheet for class 11 and class 12 physics

This mathematics sheet would be helpful for quick revision of most of maths formulas needed before class 11 and 12 physics examination. It covers quick and much needed formulas on differentiation , integration, trigonometry, AP, GP etc.

## Problem solving tricks-Right hand rules (Magnetic fields due to currents)

Right hand rule for cross product:-
Consider that c is the cross product of two vectors a and b i.e.,
c=a x b
If direction of vector a is along the x axis and that of b along z axis then direction of vector c could be find using right hand rule for cross products.

## Know How to do well in physics Board exams

So when there are few days left for your board exams , you might be thinking how to do well in physics Board exams or how do you memorise your physics formulas so that you can write all the answers that are asked in your exams easily. It is important to memorise physics formulas for exams because memorising them will increase your speed and by the end of the time you will be able to complete all your questions and still have time to revise and check for the mistakes in all of your paper.

## 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 »

## Comparison of Magnetic Force and electric forces Between two Moving Charges

Suppose two charges q1 and q2 are moving with velocities v1 and v2 \$respectively. Let r be the distance between the particles at any instant. Now two forces would be acting on each charges at this particular instant
a) Electric Force:- which is given by

## Nuclear Force – Definition | properties of Nuclear Force

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.
