    The diameter of the objective of a telescope is 0.1 m and the wavelength of the light is 6000\[Q=CV\]. Its resolving power would be approximately

    A) \[=5\times 2\]rad                           

    B) \[=10\mu C\] rad            

    C)        \[n=50\] rad      

    D)        \[r=\frac{10}{2}=5cm=5\times {{10}^{-2}}m\] rad

    Correct Answer: D

    Solution :

    Resolving power of telescope \[V=E-ir\] d = diameter of object lens = 0.1 m, and        \[=2.5-1\times 0.5=2V\] \[Q=CV\]Resolving power \[=5\times 2\]                 \[=10\mu C\] \[n=50\]radians approximately
