Question

The centripetal force acting on a mass of $m$ is $200N$, then___.(CPF - centripetal force, CFF - centrifugal force)

• A. $\text{CFF is also 200 N in terms of magnitude}$
• B. $\text{CFF is < 200 N}$
• C. $\text{CFF is > 200 N}$
• D. $\text{CFF = 0 N}$

Answer 1

The correct option is A

$\text{CFF is also 200 N in terms of magnitude}$

We know that, CPF and CFF are always equal in magnitude but opposite in direction for a body performing a uniform circular motion. Since, $CPF=200N,CFF$ has to be $200N$ in terms of magnitude. $CFF$ is an imaginary force or also known as a pseudo force which acts in opposite direction to that of $CPF$.
