Question

Calculate the upthrust force acting on a test tube if its weight in air is 0.4 N and its apparent weight in water is 0.3 N.

ScanSolve AI Tutor · Accepted Answer

The experiment describes measuring the weight of a test tube in air and then when partially immersed in water. The difference in these weights is due to the upthrust force exerted by the water.

Identify the given values.
The weight of the test tube in air is $F_1 = 0.4 \, \text{N}$ .
The weight of the test tube when immersed in water is $F_2 = 0.3 \, \text{N}$ .
State the formula for upthrust force.
The upthrust force ( $F_U$ ) is the difference between the weight of the object in air and its apparent weight when immersed in a fluid.
$F_U = F_1 - F_2$
Substitute the values into the formula and calculate the upthrust force.
$F_U = 0.4 \, \text{N} - 0.3 \, \text{N}$ $F_U = 0.1 \, \text{N}$
The upthrust force acting on the test tube is $\text{0.1 N}$ .

Calculate the upthrust force acting on a test tube if its weight in air is 0.4 N and its apparent weight in water is 0.3 N.
