Question
The figure shows different graphs between stopping potential 
and frequency (n) for photosensitive surface of cesium, potassium, sodium and lithium. The plots are parallel. Correct ranking of the targets according to their work function greatest first will be
- (i) > (ii) > (iii) > (iv)
- (i) > (iii) > (ii) > (iv)
- (iv) > (iii) > (ii) < (i)
- (i) = (iii) > (ii) = (iv)
The correct answer is: (iv) > (iii) > (ii) < (i)
between V0 and n cut the n-axis at n0.
For the given graphs 
\ (W0)(iv) > (W0)(iii) > (W0)(ii) > (W0)(i).
