Vedclass · Answer

(C) The energy gained by a charged particle accelerated through a potential difference $V$ is given by the formula: $E = qV$. Here,the charge of an electron is $q = e = 1.6 	imes 10^{-19} \ C$ and the potential difference is $V = 2.5 \ V$. Therefore,the energy gained is $E = e 	imes 2.5 \ V = 2.5 \ eV$. Since $1 \ eV$ is the energy gained by an electron when accelerated through a potential difference of $1 \ V$,the energy gained is $2.5 \ eV$.

An electron is accelerated through a potential difference of $2.5 \ V$. The energy gained by the electron is . . . . . . . (Charge of an electron = $1.6 \times 10^{-19} \ C$)
