1.	Which of the following statements is true of hydrogen atom ?A. Angular momentum `prop (1)/(n)`B. Linear momentum `prop (1)/(n)`C. Radius `prop (1)/(n)`D. Energy `prop (1)/(n)`
Answer» Correct Answer - B We know that angular momentum `L = mvr = (nh)/(2pir)r = mv = (nh)/(2pir)` Now, `r prop n^(2)` `mv = p prop (nh)/(2pi xx n^(2))` `p prop (h)/(2pin)` or `p prop (1)/(n)`
