The work function is the minimum amount of energy needed to pop an electron out of the metal. A photon at the cutoff frequency/wavelength carries exactly that minimum energy:
E = phi = h nu = h c / lambda.
E = phi = h nu = h c / lambda.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
