अवधारणा:

रैखिक और स्थिति संवेग के लिए:

[x̂, p̂x] = i   ....(1)

[p̂x, x̂] = -i   ...(2)

[x̂n, p̂x] = nxn-1 [x, p̂x]   ....(3)

[p̂xn, x̂] = npxn-1[p̂x, x̂] .....(4)

व्याख्या:

दिया गया है → [x, px2]

→ अब समीकरण (4) और (1) का प्रयोग करके,

[x, px2] = 2  [x, px]

= 2 px i

∴ विकल्प '2' सही है।

[x, px2] = 2ipx
