Dear araku
obital velocity which is derived by assumin that orbit is circular.
V=√GM/a ,this should be always perpendicual to the line joining from the planet to sun and constant .but
it is not actual case.so from these kepler's made a conclusion that oribita are not cercular but eleptical.

. 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
