An idealized ammeter is connected to a battery as shown in Fig.
E25.28. Find (a) the reading of the ammeter, (b) the current through the
resistor, (c) the terminal voltage of the battery.
Fig. E25.28.
In the circuit shown in Fig. E26.18,(a) What is the potential difference Vab between points a and b when the switch S is open and when S is closed? (b) For each resistor, calculate the current through the resistor with S open and with S closed. For each resistor, does the current increase or decrease when S is closed?
A particle with chargeis moving in a uniform magnetic fieldrole="math" localid="1655717557369"
The magnetic force on the particle is measured to berole="math" localid="1655717706597" (a) Calculate all the components of the velocity of the particle that you can from this information. (b) Are there
components of the velocity that are not determined by the measurement of the force? Explain. (c) Calculate the scalar product. What is the angle between velocity and force?
Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. These cyclotrons typically accelerate (the hydride ion, which has one proton and two electrons) to an energy of This ion has a mass very close to that of a proton because the electron mass is negligible about of the proton’s mass. A typical magnetic field in such cyclotrons is .(a) What is the speed of a ? (b) If the has energy what is the radius of this ion’s circulator orbit?
