A particle of mass \(m\) and charge \(q\) moving with velocity \(v \hat{i}\) is subjected to a uniform electric field \({E} \hat{{j}}\) . The particle will initially have a tendency to move in a circle of radius:
- \(\left(\frac{{mv}}{{qE}}\right)\) in \({x}-{y}\) plane
- \(\left(\frac{m v^{2}}{q E^{2}}\right)\) in \(x-z\) plane
- \(\left(\frac{m v^{2}}{q E}\right)\) in \(x-y\) plane
- \(\left(\frac{{mv}}{{qE}^{2}}\right)\) in \({y}-{z}\) plane
Answer
(C) ( m v^ 2 q E ) in x-y plane
