Respuesta :

F = m v2 /t   so your answer is B

Explanation:


When a body is moving in a circular path then a force acts on it and this force is directed towards the center around the moving object.  

Mathematically, F = [tex]m\frac{v^{2}}{r}[/tex]


where F = force


m = mass


v = velocity


r = radius


The term [tex]\frac{v^{2}}{r}[/tex] is the centripetal acceleration.  

Also, expression for centripetal force can be [tex]F_{c} = ma_{c}[/tex], where [tex]a_{c}[/tex] represents acceleration of centripetal force.

Whereas both the expressions F = [tex]m\frac{v^{2}}{t}[/tex] and F = [tex]m\frac{v}{r}[/tex] are not a correct equation for centripetal force.
