A proton and a Li 3 + nucleus are accelerated by the same potential. If λ Li and λ p denote the de Broglie wavelengths of Li 3 + and proton respectively, then the value of λ Li λ p is x × 10 - 1 . The value of x is _____ (Rounded off to the nearest integer) [Mass of Li 3 + = 8 . 3 mass of proton]

Correct answer

0

Step-by-step solution

λ = h 2 mqV λ Li λ p = m p e V m Li 3 e V    m Li = 8 . 3   m p λ Li λ p = 1 8 . 3 × 3 = 1 5 = 0 . 2 = 2 × 10 - 1
