Question

an electron is accelerated through a potential of 1kv . calculate the gain in its energy in i)eV ii) joule​

Answer 1

Answer:

Since the electron moves through a potential difference, the gain in kinetic energy will be equal to the Potential energy lost by the electron.

The energy can be given by the formula E=VQ, where 'E' represents potential energy in joules, and 'Q' represents charge in coulms.

E=(1kV)(1.6×10−19J)

E=1.6×10−16J
