Doubts on electric field lines and flux

Q1.Is the number of electric feild lines due to a charge DEFINITE? Q2.If it is infinite, then the electric flux due to a charge should be infinite(flux gives the num. Of elctric feild lines passing through an area)? AND Flux should be equal irrespective of the magnitude of charge. Q3.If it is definite,then it will … Continue reading Doubts on electric field lines and flux

Two atoms entangled using microwaves for the first time

Physicists at the National Institute of Standards and Technology have for the first time linked the quantum properties of two separated ions (electrically charged atoms) by manipulating them with microwaves instead of the usual laser beams, suggesting it may be possible to replace an exotic room-sized quantum computing "laser park" with miniaturized, commercial microwave technology … Continue reading Two atoms entangled using microwaves for the first time

Common Engineering Entrance Test Not Welcomed By IITs
