Electrostatic formulae


F = q E
Force= charge X Electric field
 W = qv
Work done= chargeX Pottential difference
Q = n e
Quantisation of charge
Q= number of electrons X charge of an electron ( fundamental charge is charge of an electron so total charge is an integral multipple of charge of an electron)
 F = k Q q/sqr (r)
Coulombs law to find the force between two charges

Graphs and Level curves of functions of Two variables Definitions The set of points (x,y) in the plane where a function f (x,y) has a constant value f(x,y)=c is called a level curve of f The set of all points (x,y,f (x,y)) in space, for (x,y) in the domain of f, is called the graph of f The graph of f is called the surface z=f (x,y) The equation of the following hyperbolic paraboloid is `z=50+x^2-y^2`

IBM Q computing using QIS kit had made quantum computing very simple we can embed the python code for quantum computing in IBM Q notebook without much mess. We can run the code in simulator and interestingly we can run the code even in  IBM quantum computing device!!!! Please click the link Quantum computing enthusiast  IBM Qcomputing beta version A code showing Bell state and its drawing
