Answer: Option (C) Acceleration

Explanation:
Centrifugal force is the fictitious force that we feel while moving in the circular path. Fictitious in a sense that it does not really exist, but we feel it in a non-inertial coordinate system.

Fc = [tex]\frac{mv^2}{r} [/tex]
where Fc = centrifugal force,
m = mass,
v = speed,
r = radius

If a body is acceleration, it means that its velocity is increasing. According to the equation of Centrifugal force mentioned above, Centrifugal force is directly porportional to the square of the velocity of a body. Hence, when the velocity increases (meaning there is an acceleration), the centrifugal force also increases (due to its direct relationship with the velocity of the object).

Centrifugal force increases with acceleration

Further Explanation  

  • Centrifugal force refers to the force that acts on an object in circular motion and is directed towards the axis of rotation.
  • The direction of centrifugal force is perpendicular to the direction of object displacement. Centrifugal force is responsible for keeping an object in its circular path.
  • Centrifugal force is normally equal in magnitude and opposite in direction to the centripetal force.
  • Centrifugal force is given by the formula;

[tex]Fc = \frac{-mv^2}{r}[/tex] where;

Fc is centrifugal force

M is the mass of the object or body

V is the velocity  

r is the radius of the circular path.

Factors affecting centripetal force

Velocity

  • Centrifugal force increases with an increase in the velocity or speed of the body in motion.

Mass of the body

  • An increase in the mass of the body in circular motion, increases the centrifugal force.

Radius of the circular path  

  • Centrifugal force increases with a decrease in radius of the circular path, which refers to the distance of the body from the center of the circular path.

  • Examples of centrifugal forces  
  • A car driving around a circular path or a roundabout
  • A bike making a turn, etc.
