QAIPMT-2009-Ph-2160: NEET 2009 Physics - Class 12 AIPMT-2009-Ph-2160 Solution: The figure shows a plot of photo current versus anode potential …
The figure shows a plot of photo current versus anode potential for a photo sensitive surface for three different radiations. Which one of the following is a correct statement? Curves (a) and (b) represent incident radiations of same frequency but of different intensities. Curves (b) and (c) represent incident radiations of different frequencies and different intensities. Curves (b) and (c) represent incident radiations of same frequency having same intensity. Curves (a) and (b) represent incident radiations of different frequencies and different intensities
Multiple Choice Options
- A _ 2 _ _ i 2 _ r 2 _ _ _ 1 _ _ i 1 _ r 1 _ = 0
- B _ _ 2 _ _ ( i 1 _ + i 2 _ ) R + i 2 _ r 2 _ = 0
- C _ 1 _ _ ( i 1 _ + i 2 _ ) R + i 1 _ r 1 _ = 0
- D _ 1 _ _ ( i 1 _ + i 2 _ ) R _ i 1 _ r 1 _ = 0
Step-by-Step Verified Solution
Applying Kirchhoff�s equation to the loop ABFE,
� (i 1 + i 2 )R � i 1 r 1 + _ 1 = 0
_ _ 1 � (i 1 + i 2 )R � i 1 r 1 = 0
