Question

What is the tension on a stone of mass 50 g, tied to a string of length 50 cm and rotated at a speed of 1 m/s?

0.1
100
10

Answer 1

Answer: 0.1

Step-by-step explanation:

To find the tension on the stone, we can use the centripetal force formula, which is given by F = (mv^2)/r, where m is the mass of the object, v is its velocity, and r is the radius of the circular path.

In this case, the stone is tied to a string and is moving in a circle of radius 50 cm (or 0.5 m), so we have:

F = (0.05 kg) x (1 m/s)^2 / 0.5 m

F = 0.1 N

Therefore, the tension on the string is 0.1 N.

So, the correct answer is 0.1.
