A) \[\frac{R}{2}\]
B) \[2R\]
C) \[4R\]
D) \[5R\]
Correct Answer: B
Solution :
Resolving power \[\propto \frac{1}{\lambda }\]and \[\propto \frac{1}{\sqrt{v}}\] \[\therefore \] \[R.P\propto \sqrt{v}\] \[\Rightarrow \] \[{{(R.P)}_{2}}={{(R.P)}_{1}}\times \sqrt{\frac{80kV}{20kV}}\] \[=2{{(R.P)}_{1}}\]You need to login to perform this action.
