Question: The enlarged circular inset in Fig 19 11 shows how the
The enlarged circular inset in Fig. 19.11 shows how the positive sodium ions in seawater are accelerated out the rear of the submarine to provide a propulsive force. But what about the negative chlorine ions in the seawater? Because they have charge of the opposite sign, aren’t they accelerated forward, resulting in a net force of zero on the submarine? Explain.
Answer to relevant Questions(a) Redraw the charged particle path in the apparatus diagrammed in Fig. 19.9 if the electric field of the velocity selector were reduced in magnitude. (b) Redraw the charged particle path in the apparatus diagrammed in ...The direction of any magnetic field is taken to be in the direction that a compass points. Explain why this means that magnetic field lines must leave from the north pole of a permanent bar magnet and enter its south pole. Determine the direction of the force due to the Earth’s magnetic field on an electron near the equator when the electron’s velocity is directed (a) Due south, (b) North-west, and (c) Upward. A beam of protons exits from a particle accelerator due east at a speed of 3.0 x 105 m/s. The protons then enter a uniform magnetic field of magnitude 0.50 T that is oriented at above 37o the horizontal relative to the beam ...Two identical bar magnets of negligible width are located in the x-y plane. Magnet # 1 lies on the x-axis and its north end is at while its south end is at Magnet # 2 lies on the y-axis and its north end is at y = + 1.0cm, ...
