An electron is accelerated through a potential difference of 45.5 ~V . The velocity acquired by it is ( . in ms ⁻¹ )

Step-by-step solution

As we know, Kinetic energy of electron = Energy acquired due to aligned 1 2 m_ e v²=e V₀ & potential (V₀ ) v &= 2 e V₀ m_ e &= 2 1.6 10⁻¹⁹ 45.5 9.1 10⁻³¹ &= 16 10¹² =4 10⁶ ~ms ⁻¹ aligned
