For photo-electric effect with incident photon wavelength λ\lambda , the stopping potential is V0{V}_{0} . Identify the correct variation(s)ofV0of {V}_{0} with λ\lambda and 1λ\dfrac{1}{\lambda} .For photo-electric effect with incident photon wavelength λ , the stopping potential is V _ 0 . Identify the correctFor photo-electric effect with incident photon wavelength λ , the stopping potential is V _ 0 . Identify the correctFor photo-electric effect with incident photon wavelength λ , the stopping potential is V _ 0 . Identify the correctFor photo-electric effect with incident photon wavelength λ , the stopping potential is V _ 0 . Identify the correct

Options

  1. AA conducting loop in the shape of right angled isosceles triangle of height 10 cm is kept such that the 90 ^ o vertex
  2. BA conducting loop in the shape of right angled isosceles triangle of height 10 cm is kept such that the 90 ^ o vertex
  3. CA conducting loop in the shape of right angled isosceles triangle of height 10 cm is kept such that the 90 ^ o vertex
  4. DA conducting loop in the shape of right angled isosceles triangle of height 10 cm is kept such that the 90 ^ o vertex

Correct answer

A. A conducting loop in the shape of right angled isosceles triangle of height 10 cm is kept such that the 90 ^ o vertex

Step-by-step solution

Stopping potential
eV0=hCλ−ϕe{V}_{0} = \dfrac{hC}{\lambda} - ϕ
Hence V0{V}_{0} v/s λ\lambda curve will be hyperbola and V0v/s1λ{V}_{0}v / s\dfrac{1}{\lambda} curve will be straight line with slope positive hence (A, C)
