The frequency and the intensity of a beam of light falling on the surface of a photoelectric material are increased by a factor of two. This will

A

increase the maximum energy of the photoelectrons,as will as photoelectric current by a factor of two

B

increase the maximum kinetic energy of the photo electrons and and would increase the photoelectric current by a factor of two

C

increase the maximum kinetic energy of the photoelectrons by a factor of greater than two and will have no effect on the magnitude of photoelectric current produced.

D

not produce any effect on the kinetic energy of the emitted electrons but will increase the photoelectric current by a factor of two
