Question

Mass of the proton is 1840 times that of electron. It is accelerated through a potential difference of 1 V. Find its kinetic energy. (A) 6 eV (B) 2 eV (C) 10 eV (D) 1 eV

Tardigrade Admin · Accepted Answer

The charge on a proton = e. Hence when the proton is accelerated through a potential difference of 1V, its K.E. = 1 eV.

Q. Mass of the proton is $1840$ times that of electron. It is accelerated through a potential difference of $1 V$ . Find its kinetic energy.

6 eV
