area

B

length

C

speed

D

acceleration

Text Solution

The correct Answer is:
A
`[(nh)/(2piqB)]=([mvr])/([qB]}=([mvr][v])/([F]]`
`(ML^(2)T^(-2)L)/(MLT^(-2))=L^(2)`

The stopping potential for photoelectrons from a metal surface is V_(1) when monochromatic light of frequency v_(1) is incident on it. The stopping potential becomes V_(2) when monochromatic light of another frequency is incident on the same metal surface. If h be the Planck's constant and e be the charge of an electron, then the frequency of light in the second case is
