A) the photo- current will increase
B) the kinetic energy of the electrons will increase
C) the slopping potential will decrease
D) the threshold wavelength will increase
Correct Answer: B
Solution :
In electric field photoelectrons will experience force and accelerate opposite to the field so its KE increases (ie, stopping potential will increase), no change in photoelectric current, and threshold wavelength.You need to login to perform this action.
