Help me solve the following question and make sure its correct !!

Transcribed Image Text:In an electron microscope, electrons are accelerated by passing them through a voltage difference. The kinetic energy thus acquired by the electrons is equal to
- 19
the voltage times the charge on the electron. Thus, a voltage difference of 1 volt imparts a kinetic energy of 1.602 × 10 volt-coulomb or 1.602 × 10¯ 19 J.
