Answer :

The energy of the object is conserved because the obly force acting on the object is gravitational force which is a conservative force . The conservation of momentum though DOES NOT holds good as the force of gravity acts in the direction of motion of the object thus resulting in a reduction of the momentum of the object during its upward journey.

. 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
