Round the following numbers to 2 significant digits. A(a) 3472, (b) 84.16, (c) 2.55 and (d) 28.5 and (d) 28.5.
1 Answer
Aditi Chauhan
Sol. a) In the value 3472, after the digit 4, 7 is present. Its value is greater than 5.
So, the next two digits are neglected and the value of 4 is increased by 1.
∴ value becomes 3500
b) value = 84
c) 2.6
d) value is 28.

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
