Question

Find the value of A and B if AB+BA=DAD?

Answer 1

Answer:

The work function of a certain metal is (hC)/lambda_(0). When a monochromatic light of wavelength lambda lt lambda_(0) is incident such that the plate gains a total power P. If the efficiency of photoelectric emission is eta% and all the emitted photoelectrons are captured by a hollow conducting sphere of radius R already charged to potential V, then neglecting any interaction of potential of the sphere at time t is:
