A particle with charge 7.26 * 10-8 C is moving in a region where there is a uniform 0.650-T magnetic field in the +x-direction. At a particular instant, the velocity of the particle has components vx = -1.68 * 104 m/s, vy = -3.11 * 104 m/s, and vz = 5.85 * 104 m/s. What are the components of the force on the particle at this time?

Short Answer

Expert verified

The force components areFx=0,Fy=2.76×103N,Fz=1.47×103N

Step by step solution

01

Magnetic force

The magnetic force is given by

FB=q(v×B)

02

Determine the magnetic force components acting on that particle

The magnetic force acting on a charged particle is

FB=q(v×B)

Therefore,

F=qv×B=qi^j^k^vxvyvzBxByBz

Therefore, the components of the force are

Fx=q(vyBzvzBy)=0AndFy=q(vzBxvxBz)=qvzBx=(7.26×108C)(5.85×104m/s)(0.650T)=2.76×103N

And,

Fz=q(vxByvyBx)=qvyBx=(7.26×108C)(3.11×104m/s)(0.650T)=1.47×103N

Therefore, the force components areFx=0,Fy=2.76×103N,Fz=1.47×103N

An idealized voltmeter is connected across the terminals of a15.0-Vbattery, and arole="math" localid="1655719696009" 75.0-Ω appliance is also connected across its terminals. If the voltmeter reads11.9V (a) how much power is being dissipated by the appliance, and (b) what is the internal resistance of the battery?

An alpha particle (a He nucleus containing two protons and two neutrons and having a mass of 6.64×10-7kg) travelling horizontally at 35.6km/senter a uniform, vertical,1.80-T magnetic field.(a) What is the diameter of the path followed by this alpha particle? (b) what effect does the magnetic field have on the speed of the particle? (c) What are the magnitude and direction of the acceleration of the alpha particle while it is in the magnetic field? (d) explain why the speed of the particle does not change even though an unbalanced external force acts on it.

An electron moves at 1.40×106m/sthrough a regionin which there is a magnetic field of unspecified direction and magnitude 7.40×10-2T. (a) What are the largest and smallest possible magnitudes of the acceleration of the electron due to the magnetic field? (b) If the actual acceleration of the electron is one-fourth of the largest magnitude in part (a), what is the angle
between the electron velocity and the magnetic field?

A typical small flashlight contains two batteries, each having an emf of1.5V, connected in series with a bulb having resistance17Ω. (a) If the internal resistance of the batteries is negligible, what power is delivered to the bulb? (b) If the batteries last for1.5hwhat is the total energy delivered to the bulb? (c) The resistance of real batteries increases as they run down. If the initial internal resistance is negligible, what is the combined internal resistance of both batteries when the power to the bulb has decreased to half its initial value? (Assume that the resistance of the bulb is constant. Actually, it will change somewhat when the current through the filament changes, because this changes the temperature of the filament and hence the resistivity of the filament wire.)

You want to produce three 1.00-mm-diameter cylindrical wires,

each with a resistance of 1.00 Ω at room temperature. One wire is gold, one

is copper, and one is aluminum. Refer to Table 25.1 for the resistivity

values. (a) What will be the length of each wire? (b) Gold has a density of1.93×10-4kgm3.

What will be the mass of the gold wire? If you consider the current price of gold, is

this wire very expensive?
