When photon of wavelength `lambda_(1)` are incident on an isolated shere supended by an insulated , the corresponding stopping potential is found to be `V`. When photon of wavelength `lambda_(2)` are used , the orresponding stopping potential was thrice the above value. If light of wavelength `lambda_(3)` is used , carculate the stopping potential for this case.

A

`(hc)/(e)[1/(lambda_(3))+(1)/(2lambda_(2))-(1)/(lambda_(1))]`

B

`(hc)/(e)[1/(lambda_(3))-(1)/(lambda_(2))-(1)/(lambda_(1))]`

C

`(hc)/(e)[1/(lambda_(3))+(1)/(lambda_(2))-(1)/(lambda_(1))]`

D
