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

Options

A. `(hc)/(e)((1)/(lambda_(3))+(1)/(2lambda_(2))-(1)/(lambda_(1)))`
B. `(hc)/(e)((1)/(lambda_(3))+(1)/(2lambda_(2))-(1)/(2lambda_(1)))`
C. `(hc)/(e)((1)/(lambda_(3))+(1)/(lambda_(2))+(1)/(lambda_(1)))`
D. `(hc)/(e)((1)/(lambda_(3))-(1)/(lambda_(2))-(1)/(lambda_(1)))`

Answer

B
