Given that

Photoelectric cut-off voltage V = 1.5 V

Charge of electron e = 1.6*10^{-19} C

Step 1: Set up an equation for maximum kinetic energy and find that

By conservation of energy, kinetic energy has to be equal to the change in potential energy.

K.E = eV

K.E = 1.6*10^{-19} * 1.5

K.E = 2.4 * 10^{-19}

Thus, the maximum kinetic energy of the photoelectron emitted K.E = 2.4 * 10^{-19} J
