two metals A and B have work functions 4 eV and 10 eV respectively. which metal has higher thersold frequency?
1 Answer
Apoorva Arora
Threshold frequency is the minimum frequency at which photoelectric effect can be observed. So, the metal B has the higher work function and hence the higher threshold frequency.
Thanks and Regards

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
