A) \[1\times {{10}^{6}}\]
B) \[6.56\times {{10}^{6}}\]
C) \[3.28\times {{10}^{6}}\]
D) \[3.28\times {{10}^{5}}\]
Correct Answer: C
Solution :
: Here, Diameter of the objective, \[D=200cm=200\times {{10}^{-2}}m=2m\] Wavelength of light, \[\lambda =5000\overset{\text{o}}{\mathop{\text{A}}}\,=5000\times {{10}^{-10}}m=5\times {{10}^{-7}}m\] Resolving power of a telescope \[=\frac{D}{1.22\lambda }\] \[=\frac{2}{1.22\times 5\times {{10}^{-7}}}=\frac{4}{1.22}\times {{10}^{6}}=3.28\times {{10}^{6}}\]
