A) \[500\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[2\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[0.5\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[0.02\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
\[\lambda =\frac{h}{m\upsilon }\] Here, \[h=6.6\times {{10}^{-34}}Js\]and momentum \[m\upsilon =3.3\times {{10}^{-24}}kg\,m\,{{\sec }^{-1}}\] Thus \[\lambda =\frac{6.6\times {{10}^{-34}}}{3.3\times {{10}^{-24}}}\] \[=2\times {{10}^{-10}}m=2\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
