As the measured value is 3.50 cm, the least count must be 0.01 cm = 0.1 mm
For vernier callipper with MSD = 1 mm and 9 MSD = 10 VSD,
Least count = 1 MSD – 1 VSD = 0.1 mm
For vernier callipper with MSD = 1 mm and 9 MSD = 10 VSD,
Least count = 1 MSD – 1 VSD = 0.1 mm

Instrument Used: A Vernier Calliper
Explanation:
To determine the instrument used to measure the length of the rod, let's analyze the given options:
a) A metre scale: A metre scale typically measures lengths in centimeters or millimeters. However, since the recorded measurement is given as 3.50 cm, it is unlikely that a metre scale was used. Therefore, option a) can be ruled out.
b) A vernier calliper where the 10 divisions in vernier scale matches with 9 divisions in main scale and the main scale has 10 divisions in 1 cm: This option seems plausible because a vernier calliper is capable of measuring lengths with high precision. The given details about the 10:9 ratio between the vernier and main scales are consistent with the design of a vernier calliper. Hence, option b) is a likely candidate.
c) A screw gauge having 100 divisions in the circular scale and pitch as 1 mm: A screw gauge is primarily used to measure small lengths, typically in the sub-millimeter range. The recorded measurement of 3.50 cm is much larger than what a screw gauge is typically used for. Therefore, option c) can be ruled out.
d) A screw gauge having 50 divisions in the circular scale and pitch as 1 mm: Similar to option c), this option involves a screw gauge that is intended for measuring small lengths. The recorded measurement of 3.50 cm is significantly larger than what a screw gauge is typically used for, so option d) can also be eliminated.
Conclusion:
By process of elimination, the most likely instrument used to measure the length of the rod is a vernier calliper as described in option b). This instrument allows for precise measurements and the given details about the scale divisions align with the design of a vernier calliper.
