Question

Uncertainity in position of a particle of 25 g in space is 10–15 m. Hence, Uncertainity in velocity (in m.sec–1) is : (plank’s constant, h = 6.6 ´ 10–34Js)

• A. 2.1 ´ 10–18
• B. 2.1 ´ 10–34
• C. 0.5 ´ 10–34
• D. 5.0 ´ 10–24

Answer 1

Answer: (A)

2.1 ´ 10–18

Answer 2

}{\therefore \Delta v = 2.1 \times 10^{- 18}ms^{- 1}.}$$
