Work done in accelerating a proton
The mass of a proton is 1840 times that of an electron. it is accelerated to a potential difference of 1kV. find the amount of work done in process. (Ujjwal Sharma asked)
Answer
The work done = the KE acquired = eV=1.6 x 10-19 x 1000 = 1.6 x 10-16 J

Please note that the energy acquired as well as the work done in the case of an electron as well as a proton is the same, but the speed acquired by them will be different due to the difference in mass.
You can see it by the formula work done = KE acquired
