PYQ NEET- Modern Physics General Introduction
Kinetic energy gained = 1/2mv2 = eV = 1.602 x 10-19 x 1000 = 1.602 x 10-16 Joule
Speed = √(2KE/m) = √(2 x 1.602 x 10-16/9.1 x 10-31) = 5.92 x 106 m/s
- An electron is accelerated through a potential difference of 1000 V. Its speed will be
5.92 x 106 m/s
