If the radii of circular paths of two particles of same mass are in the ratio of \(1: 2\), then to have a constant centripetal force, the ratio of their speeds should be
- A \(4: 1\)
- B \(1: \sqrt{2}\)
- C \(1: 4\)
- D \(\sqrt{2}: 1\)
Answer & Solution
Correct Answer
(B) \(1: \sqrt{2}\)
Step-by-step Solution
Detailed explanation
Centripetal force \(F=\frac{m v^2}{R}\) or \(v=\sqrt{\frac{F R}{m}}\) or , \(v \propto \sqrt{R}\) as mass ' \(m\) ' and force ' \(F\) ' is constant. \(\frac{R_1}{R_2}=\frac{1}{2}\)…
