Question

solve it I want really urgent​

Answer 1

ⒽⓁⓄ ⓜⓐⓣⓔ

ans :- maximum kinetic energy for both metals depend linearly on frequency .

explanation :- 1/2mv^2max = h(v-Vo)

since H and Vo are constant , therefore

1/2mv^2 max is directly proportional to v.

Answer 2

SOLUTION

Option (b)☑️

Maximum kinetic energy for both the metals depend linearly on the frequency.

Explanation:

Stopping potential equals to Maximum kinetic energy.

Since stopping potential is varying with the frequency. Therefore max. KE for both the metals also very linearly with frequency.

hope it helps ☺️
