Two identical photocathodes receive light of frequency `f_(1) and f_(2)` if the velocities of the photo electrons (of mass `m`) coming out are respectively `v_(1) and v_(2)` then

A

`v_(1)-v_(2)=[(2h)/(m)(f_(1)-f_(2))]^(1//2)`

B

`v_(1)^(2)-v_(2)^(2)=(2h)/(m)(f_(1)-f_(2))`

C

`v_(1)+v_(2)=[(2h)/(m)(f_(1)+f_(2))]^(1//2)`

D

`v_(1)^(2)+v_(2)^(2)=(2h)/(m)(f_(1)+f_(2))`
