NEGATIVE CHARGED PARTICLE4.THEY REVOLVE AROUND NUCLEUS5.POSSES BOTH WAVE AND PARTICLE NATUREBALLISTICSBALLISTICS IS THE SCIENCE OF MECHANICS THAT DEALS WITH THE LAUNCHING ,FLIGHT,BEHAVIORAND EFFECTS OF PROJECTILES,ESPECIALLY BULLETS,GRAVITY BOMBS, ROCKETS,OR THE LIKE; THE SCIENCE OR ART OF DESIGNING AND ACCELERATING PROJECTILES SO AS TO ACHIEVE A DESIRED PERFORMANCEINTRODUCTION ELECTRON BALLISTICS IS THE BRANCH OF ELECTRONICS THAT DEALS WITH THE MOTION OF FREE ELECTRON OR OTHER ELECTRIC PARTICLE IN ELECTRIC OR MAGNETIC FIELDSMOTION OF ELECTRONELECTRIC FIELDMAGNETIC FIELDTRANSVERSE AND PERPENDICULARPARALLEL AND LONGITUDINALAT AN ACUTE ANGLETRANSVERSE AND PERPENDICULARPARALLEL AND LONGITUDINALAT AN ACUTE ANGLEPARABOLIC PATHSTRAIGHT OR LINEAR PATHPARABOLIC PATHCIRCULAR PATH BETH'S LAWTHE REFRACTION OF AN ELECTRON BEAMACROSS THE EQUIPOTENTIAL SURFACE, SEPARATING THE TWO REGIONS OF DIFFERENT POTENTIALS. SINCE, THIS PHENOMENIN IS ANALOGOUS TO REFRATION OF LIGHT, IT IS CALLED ELECTRON DIFFRACTIONHELICAL PATHCIRCULAR PATHMAGNETOSTATIC DEFLECTIONTHE DEFLECTION IN THE PATH OF THE CHARGED PARTICLE BY A MAGNETIC FIELD LORENTZ EQUATIONWHEN THE CHARGED PARTICLE OF MASS M AND CHARGE Q MOVES WITH A VELOCITY V IN A REGION WHERE THERE ARE BOTH ELECTRIC AND MAGNETIC FIELDS,IT WILL EXPERIENCE BOTH AN ELECTRIC FORCE qE AND A MAGNETIC FORCE q(V*B), SO THAT THE TOTAL FORCE IS THE VECTOR SUM OF THE ELECTRIC FORCE AND MAGNETIC FORCE.ELECTRON LENS OR ELECTROSTATIC LENSPRINCIPLE: A STREAM OF ELECTRON BENDS AT EACH EQUIPOTENTIAL SURFACE WHEN IT TRAVELS THROUGH A NON-UNIFORM ELECTRIC FIELD
