The electric field component of an $EM$ radiation varies with time as $E = a(\cos \omega_{0} t + \sin \omega t \cos \omega_{0} t)$,where '$a$' is a constant,$\omega = 10^{15} \text{ s}^{-1}$,and $\omega_{0} = 5 \times 10^{15} \text{ s}^{-1}$. This radiation falls on a metal whose stopping potential is $2 \text{ V}$. Which of the following statement$(s)$ is/are true? $(h = 6.62 \times 10^{-34} \text{ J s})$

• A
  For light of frequency $\omega$,the photoelectric effect is not possible.
• B
  The stopping potential vs. frequency graph will be a straight line.
• C
  The work function of the metal is $2 \text{ eV}$.
• D
  The maximum kinetic energy of the photoelectrons is $1.95 \text{ eV}$.
