Question 1 of 19

Metallic sphere of radius is removed from other bodies, and is irradiated with the radiation of wavelength Lambda, so that it is capable of causing Photoelectric effect.

Select Your Answer:

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

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

The kinetic energy of the most energetic electron emanating from the Sphere will keep on declining with time

The kinetic energy of the most energetic electrons emitted from this sphere initially will be independent of the radius of the sphere
