  2. BThe graph between 1 / λ and stopping potential (V) of three metals having work function φ_1, φ_2 and φ_3 in an
  3. CThe graph between 1 / λ and stopping potential (V) of three metals having work function φ_1, φ_2 and φ_3 in an
  4. DThe graph between 1 / λ and stopping potential (V) of three metals having work function φ_1, φ_2 and φ_3 in an

Correct answer

A. The graph between 1 / λ and stopping potential (V) of three metals having work function φ_1, φ_2 and φ_3 in an

Step-by-step solution

For a freely falling body, v2−u2=2gx(∴u=0)v^{2}-u^{2}=2 g x \quad(\therefore u=0) Therefore, v2=2gx\quad v^{2}=2 g x or x=v22gx=\frac{v^{2}}{2 g} Thus, graph will be a parabola, symmetric along +ve XX-axis
