Why is the belt of a Van de Graaff generator made of insulating material?
1 Answer
Saurabh Koranglekar
The Van de graaff generator has a long narrowendless belt made of insulating material like rubber or silk because the there should be no loss of potential difference/voltage.. It can build up high voltages of order of a few million volts..Also since it carries +ve charge to another brush connected to large shell, it shd. of be insulating nature..

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
