AP EAMCET · PHYSICS · Motion In Two Dimensions
If mass, speed and radius of the circular path of the particle are increased by \(100 \%\), then the necessary force required to maintain the circular path will have to be increased by
- A \(100 \%\)
- B \(250 \%\)
- C \(300 \%\)
- D \(400 \%\)
Answer & Solution
Correct Answer
(C) \(300 \%\)
Step-by-step Solution
Detailed explanation
Centripetal force is given as \(F=\frac{m v^2}{r}\) where, \(m=\) mass, \(v=\) velocity and \(r=\) radius. \(\frac{F_2}{F_1}=\frac{m_2}{m_1} \cdot\left(\frac{v_2}{v_1}\right)^2 \cdot\left(\frac{r_1}{r_2}\right)\) ...(i) When, mass, speed and radius of circular path of particle…
