The term "physical content or quantity" usually refers to the number and its units, not just the dimensions. For example, the *value* of an object`s temperature is said to be a physical quantity.For example, the ratio of the temperature of a desk to the temperature of a chair (both measured in K) has the same units or dimensions as the ratio of the water in my glass to the water in my body (both measured in liters). But they don`t represent teh same physical content.Moreover, even potential and kinetic energy of an object has same units and dimensions but they represent totally different physical contents.

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
