In aphotocell frequency of incident radiation is increased by keeping other factors constant `(vgtv_(0))`, the stopping potential

Options

A. decreases
B. increases
C. becomes zero
D. first decreases and then increases

Answer

B

Explanation

We know that,
`eV_(0)=hv-hv_(0)`
`or" "eV_(0)=h(v-v_(0))`
`or" "V_(0)=(h)/(e)(v-v_(0))`
`or" "V_(0)=(h)/(e)(v-v_(0))`
Here, `V_(0)` = stopping potential
and V= frequency of incident radiation.
Therefore, stopping potential is directly proportional to the frequency of incident radiation. Hence, stopping potential `V_(0)` is increased.
