A metallic sphere of radius r remote from all other bodies is irradiated with a radiation of wavelength λ which is capable of causing photoelectric effect.

Select all that apply

• Option A

  the maximum potential gained by the sphere will be independent of its radius.

• Option B

  the net positive charge appearing on the sphere after a long time will depend on the radius of the sphere.

• Option C

  the maximum kinetic energy of the electrons emanating from the sphere will keep on declining with time.

• Option D

  the kinetic energy of the most energetic electrons emanating from the sphere initially will be independent of the radius of the sphere.
