Question 44: How many grams is an approximate mass of a textbook (Textbook) of Physics 6? Try to weigh the textbook and choose the correct answer.

Physics textbook 6 has a very small mass in the range of 100g to 200g. To weigh the textbooks, we use a Rober-valve scale, at first we adjust it so that when we are not weighed, the balance lever must be balanced, the needle is only right in the middle. Place the book on the left weighing pan. Place a number of weights on the other side of the balance plate and adjust the stallion so that the lever is level, the needle is in the center of the scale. The total mass of the weights on the pan plus the stallion’s number will be the mass of the book.
