Beam Balance
 1) In the experiment of a beam balance, a metallic bob is placed in one of the pan and it gets balanced by putting the weights 50 g, 1 g, 200 mg and 10 mg. What is the mass of the bob is : 51.210 g 51.201 g 49.190 g 49.199 g

 2) The minimum weights, available in the main 'weight box' and the 'fractional weight box', commonly used in the laboratory are, respectively: 1 g and 10 m g 10 g and 1 mg 1 g and 1 mg 10 g and 10 m g

 3) The quantity of matter possessed by the body is called? Weight Density Mass Volume

 4) The mass required to change the resting point of a beam balance by one division is called? Specificity Visibility Sensibility Stability

 5) The sensibility of a beam balance is 0.003243 and R0 is 8.916667. When an object of 8.72 g wt is placed in the left pan and it is counter poised with weights in the right pan, the turning points noted are as follows. What is the correct weight of the object placed in the pan? 8.72 8.71 8.7222 8.722

 6) The resting point R0 of a beam balance is 9.01 and the resting point of the same when a 10 mg is placed in its right pan is 8.9. Then, what is the sensibility of the beam balance? 0.009 .909 .99 0.09

 7) What is the S.I unit of weight? Milligram Kilogram Newton Gram

 8) The force with which the body is attracted by the earth towards its centre is___________. Centrifugal force Acceleration due to gravity Mass of a body Weight of a body

 9) What is the relationship between gravitational mass and inertial mass of a body? Gravitational mass is greater than inertial mass Inertial mass is greater than gravitational mass. Two masses are found to be equal. None of the above.

 10) What is the principle behind the working of a beam balance? Law of Inertia Law of Moments Gravitational Law Hooke’s Law
