A) \[\text{1}\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[\text{10}\overset{\text{o}}{\mathop{\text{A}}}\,\]
C) \[\text{100}\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[\text{1000}\overset{\text{o}}{\mathop{\text{A}}}\,\]
Correct Answer: B
Solution :
Resolving power or limit of resolution is the ability to distinguish two close points as distinct. It is calculated as \[m=\frac{0.61\lambda }{NA}\] \[\text{NA}\,\text{=}\,\text{Numerical Aperature}\text{.}\] The resolving power of electron microscope is \[2-10\overset{\text{o}}{\mathop{\text{A}}}\,.\]
