Answer : The correct option is, X : radius and Y : tangential speed
Explanation :
Centripetal force : It is defined as a force which acts on the object to keep the object moving along a circular path.
Formula for centripetal force :
[tex]F_c=\frac{m\times V^2}{r}[/tex]
where,
[tex]F_c[/tex] = centripetal force
m = mass
r = radius
V = tangential speed
The quantity belong in cell X is radius and in the cell Y is tangential speed
Hence, the correct option is, X : radius and Y : tangential speed
