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..

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
deviation (a) at 40 latitude, (b) at the poles, and (c) at the equator

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
