Physics · Class 12 · CBSE — Moving Charges and Magnetism
Two charged particles, \(P\) and \(Q\) , each having charge \(q\) but of masses \(m_1\) and \(\mathrm{m}_2\) , are accelerated through the same potential difference V . They enter a region of magnetic field \(\vec{B}(\perp \vec{v})\) and describe the circular paths of radii a and b respectively. Then \(\left(\frac{m_1}{m_2}\right)\) is equal to:
- \(\frac{\mathrm{a}}{\mathrm{b}}\)
- \(\frac{\mathrm{b}}{\mathrm{a}}\)
- \(\left(\frac{a}{b}\right)^2\)
- \(\left(\frac{\mathrm{b}}{\mathrm{a}}\right)^2\)
Answer
(C) ( a b )^2
