## JEE advanced physics questions

Question 1A ball of mass 100 g is projected vertically upwards from the ground with velocity 49 m/s. At the same time other identical ball is dropped from a height of 98 m to fall freely along the same path as followed by the first ball. After some time two balls collide and stick together […]

## Stable unstable and neutral equilibrium Questions for JEE Examination

What is Equilibrium

A rigid body is supposed to be in equilibrium if there is no change in translational motion and no change in rotational motion

The general conditions for equilibrium are as follows

(i) The total force must be zero

(ii) The total torque about any axis must be zero.

In many cases it is convenient to consider torques about axes through the centre of gravity.

Types of equilibrium

We can divide the equilibrium into two categories With respect to the state of a body

1. Static equilibrium.

2. Dynamic equilibrium.

## The flow of charge: definition and explanation

The flow of charge in an electric circuit signifies the existence of electric current in that circuit. We can define electric current as the rate of flow of electric charges (electrons) in a conductor (for example copper or metallic wire). Flow of charge definition The flow of charge is the process of supplying or adding […]

## Difference between resistance and resistivity

In this article, we will learn about the difference between resistance and resistivity. Students first come across these terms while studying Electricity where the concept of electric current, resistance and resistivity are introduced. For the basic introduction visit our notes on electricity. TLDR – Too Long Don’t ReadBoth resistance and resistivity describe how difficult it […]

## Algebraic Identities

What is an Identity An identity is an equality, which is true for all values of the variables in the equality. While an equation is true only for certain values of its variables. An equation is not an identity. Example x+ 2 =5Now this is true for x=3 only.So this is not an identity$(x+1)^2 = […]
