An electron (charge = 1.6×10−19 coulomb) is accelerated throug

Question

An electron (charge =

1.6 \times 10^{- 19}

coulomb) is accelerated through a potential of 1,00,000 volts. The energy required by the electron is

Options:

A . 1.6×10−24 joule

B . 1.6×10−14 joule

C . 0.53×10−14 joule

D . 1.6×10−14 joule

Answer: Option D
:
D
Energy = qV=

1.6 \times 10^{- 19} \times 100000 = 1.6 \times 10^{- 14} J
