Two identical photo-cathodes receive light of frequencies f₁ and f₂. If the velocities of the photo electrons (of mass m) coming out are respectively v₁ and v₂, then

(A) v₁² - v₂² = 2h/m(f₁ - f₂)

(B) v₁ + v₂ = [ 2h/m(f₁ + f₂) ]^(1/2)

(C) v₁² + v₂² = 2h/m(f₁ + f₂)

(D) v₁ - v₂ = [ 2h/m(f₁ - f₂) ]^(1/2)
