The figure shows the variation of stopping potential \({V}_0\) with frequency \(v\) of incident radiation, for three materials \({M}_1, {M}_2\) and \({M}_3\) with work functions \(\phi_1, \phi_2\) and \(\phi_3\) respectively. Then:
- \(\phi_1>\phi_2>\phi_3\)
- \(\phi_2>\phi_3>\phi_1\)
- \(\phi_3>\phi_2>\phi_1\)
- \(\phi_2>\phi_1>\phi_3\)
Answer
(A) _1> _2> _3
