Answer:
halved
Explanation:
radius = r
velocity = v
let the mass is m
Force is centripetal force
F = mv²/r ... (1)
Now, r' = r/2 and v' = v/2 So,
F' = m v² x 2 / 4 x r
F' = mv²/2r
F' = F/2 (from equation (1)
Thus, the force is halved.
Answer:
Explanation:
Considering aircraft of mass m is moving with constant velocity v in a trajectory of radius r then the force acting on the body is centripetal force.
Centripetal force will acts on a body when a particle moves in a circular trajectory
It is given by
[tex]F_c=\frac{mv^2}{r}[/tex]
if both speed and radius is reduced to half then force become
[tex]F'_c=\frac{m\times (0.5v)^2}{0.5r}[/tex]
[tex]F'_c=0.5\cdot \frac{mv^2}{r}[/tex]
Force will reduced to half
