A trader weighs 8.99 quintals of iron rods with the help of kilogram weights. Find the smallest possible limiting relative error.

A pole is measured with a scale marked in centimetres.If the length of the pole is 16.52 m,then find the smallest possible limiting absolute error.

A solenoid 600 mm long has 50 turns on it and its wound on an iron rod 7.5 mm radius. Find the flux through the solenoid when the current in it is 3A. The relative permeability of iron is 600.

A train weighing 1000 quintals is running on a level road with a unifrom speed of 72km//h If the frictional resistance amounts to 50g wt. per quintal find power in watt, take g = 9.8ms^(2) .

The relative density of material of a body is found by weighting it first in air and then in water . If the weight in air is ( 5.00 +- 0.05) N and the weight in water is (4.00 +- 0.05) N . Find the relative density along with the maximum permissible percentage error.
