  1. AWhich one of the following biofertilizer makes the plant associated with them grow luxuriantly in less irrigated lands?
  2. BWhich one of the following biofertilizer makes the plant associated with them grow luxuriantly in less irrigated lands?
  3. CWhich one of the following biofertilizer makes the plant associated with them grow luxuriantly in less irrigated lands?
  4. DWhich one of the following biofertilizer makes the plant associated with them grow luxuriantly in less irrigated lands?

Correct answer

D. Which one of the following biofertilizer makes the plant associated with them grow luxuriantly in less irrigated lands?

Step-by-step solution

According to photoelectric equation E_{k}=h v-h v_{0} If the energy of photon (hv)(h v) is less than the work function \left(h v_{0}\right)ofmetallicsurface,thenelectronswillneverbeejectedfromsurfaceregardlessofintensityofincidentlightAlso,fromEq.(i),whenv=v0,Ek=0of metallic surface, then electrons will never be ejected from surface regardless of intensity of incident light Also, from Eq. (i), when v=v_{0}, E_{k}=0\thereforeGraph(d)representsvariationofGraph (d) represents variation ofE_{k}withwithv
