Define electronVolt and convert it into Joule unit. |

Answer» Solution :If an electron with charge q =e=`1.6xx10^(-19)` C is accelerated by a potential difference of 1 volt it would gain energy `=qDeltaV` `=1.6xx10^(-19)xx1` `[ because DeltaV =1V]` `=1.6xx10^(-19)`j This unit of energy is defined as 1 electron voltor 1 eV. Definition:"if an electron according through a potential difference of ONE volt the difference in potential (or kinetic) energy of an electron is known as one electron volt". This unit are most commonly used in atomic , nuclear and particle physics. Multiplier and submultiplier of eV: `I meV 1.6 xx 10^(-22) J ` `1 KEV = 1.6 xx 10^(-16)`j `1 Me = 1.6xx10^(-13) J` `1 GE V = 1.6xx10^(-10) J` `1 TEV= 1.6xx10^(-7) `J |
