Solution
Verified by Toppr

The threshold frequency of metal plate P is lesser than that of Q.
Since λ1ν, the threshold wavelength of metal plate P is greater than that of Q.
The work function of a metal is given as
W0=hν0
Since the threshold frequency of metal Q is greater, the work function it is also greater than that of P.
