Some charged particles in a bubble chamber are seen to move in spirals due to
A)decreasing magnetic field.
B)decreasing electric charge.
C)perspective and parallax.
D)energy dissipation.

Question

Quizplus · Accepted Answer

Charged particles in a bubble chamber move in spirals primarily due to energy dissipation. As they move through the medium, they lose energy, causing their speed and hence their radius of curvature to decrease, resulting in a spiral path.
