Question

----------------
Two different forces, acting on the same object, are measured. One force is 2.0031 N and the other force, in the same direction, is 3.12 N. These are the only forces acting on the object. Find the total force on the object to the correct number of significant figures.

Answer 1

Answer:

Thank you for the point sorry

Answer 2

Given: Two forces of 2.0031 N and 3.12 N are acting in the same direction.

To find: The total force on the object to correct number of significant figures

Explanation: Since, the forces are acting in the same direction, the forces will add up to give a resultant force.

3.12 can be written as 3.1200 because it will then be easier to add with 2.0031.

Adding, 2.0031+ 3.1200 we get the sum as 5.1231.

Now, 2.0031 has 4 significant figures after decimal while 3.12 has only 2 significant figures after decimal so the answer 5.1231 should have only 2 significant figures after decimal.

Therefore, 5.1231 becomes 5.12 when rounded off to 2 significant figures after decimal.

Therefore, the total force on the object to the correct number of significant figures is 5.12 N.
