Final answer:
"False". Changing the mass, velocity, or radius of an object in a classic circular force lab does not affect the force exerted on it.
The correct answer is b.
Step-by-step explanation:
b. False
The correct answer is b. False. In a classic circular force lab, the change in mass, velocity, and radius does not affect the force.
The force applied to an object moving in a circular path, also known as the centripetal force, is directly proportional to the mass of the object and the square of its velocity, but inversely proportional to the radius of the circular path.
Therefore, changing the mass, velocity, or radius of the object would not change the force exerted on it.
The correct answer is b.
