Question

Johanna makes the table below to organize her notes about centripetal forces. Which type of force should she place in the cell marked X?

Answer 1

X: radius,
Y: tangental speed.

Answer 2

Answer: The correct answer is Option 2.

Step-by-step explanation:

Centripetal force is defined as the force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

Mathematically,

`F_c=(mv^2)/(r)`

Where,

`F_c` = centripetal force

m = mass of the object

v = tangential velocity

r = radius of the path

From the above relation, X corresponds to the radius and Y corresponds to the tangential velocity.

Hence, the correct answer is option C.
