JEE Main 2022 Physics question
The equation = 1.227/x nm can be used to find the de- Broglie wavelength of an electron. In this equation x stands for: Where m = mass of electron, P = momentum of electron, K = Kinetic energy of electron, V = Accelerating potential in volts for electron
Answer: (D)
Solution
For an electron accelerated through a potential V, the de Broglie
