Answer:
The correct solution will be "271.95 N".
Explanation:
The given values are:
velocity Â
v = 3.5 m/s
mass
m = 9.0 kg
r = 0.6 m
According to the question:
⇒ [tex]F_{branch}=F_{gravity}+F_{centrifugal}[/tex]
⇒       [tex]=mg+\frac{mv^2}{r}[/tex]
On substituting the values, we get
⇒       [tex]=9\times 9.8+\frac{9\times (3.5)^2}{0.6}[/tex]
⇒       [tex]=88.2+\frac{110.35}{0.6}[/tex]
⇒       [tex]=271.95 \ N[/tex]
