Question

If Planck’s constant is denoted by h and electronic charge by e, then photoelectric effect allows determination of:
  1. Only e
  2. Both h and e
  3. Only h/e
  4. Only h

A
Only h
B
Both h and e
C
Only h/e
D
Only e
Solution
Verified by Toppr

The correct option is D Only h/e
In photoelectric effect we can know only the stopping potential.
Stopping potential =(hcλϕ)/e
=hceλϕ/e
So, we can determine only h/e because we know stopping potential, frequency and work function of the metal.

A 50 litre vessel is equally divided into three parts with the help of two stationary semi permeable membrane(SPM). The vessel contains 60g H2 gas in the left chamber, 160g O2 in the middle and 140g N2 in the right one. The left SPM allows transfer of only H2 gas while the right one allows the transfer of both H2 andN2. The final ratio of pressure in the three chambers:
