Question

The ratio of slopes k max vs v and v vs k

Answer 1

Answer:

here   idk if its good

Explanation:

[v= frequency, Kmax= maximum kinetic energy, v0= stopping potential] A

Answer 2

Answer:

e - charge of electron

Explanation:

hv = hv0  + ev0

​ divide by e

v0 = (h/e)v - (h/e)v0

On comparing this equation with the straight line equation, i.e y=mx+c

The slope of v0  vs v is (v0  is stopping potential)

(slope)1 = h/e ..............(1)

or Kmax  = hv−hv0

(slope)2 = h ................(2)

eqn (2)/(1)

ans; e
