A uniform magnetic field with a magnitude of 1.2 10 -23 × T points vertically upward through a laboratory chamber. A proton with a velocity of 3.2 10 × -7 m/s enters the chamber moving horizontally from south to north. (a) What is the magnitude of the magnetic force on the proton? (b) What is the direction of the magnetic force on the proton?

Answer from: RipoldSmellypoop47

The magnitude of the magnetic force on this proton would be approximately $6.1 \times 10^{-49}\; \rm N$ .

The direction of the magnetic force on this proton will point to the east.

Explanation:

(a)

Let denote the size of the charge. Let denote the velocity of this charge. Let denote the strength of a uniform magnetic field. Assume that this charge is moving through this magnetic field. Let the angle between

$F = q\, v\, B \, \cos\theta$ .

The direction of the velocity of the proton in this question is horizontal. On the other hand, the magnetic field in this question is oriented vertically. As a result, the angle between the and the here would be $90^\circ$ .

Look up the size of the charge on a proton (the elementary charge) in Coulombs:

$q \approx 1.60 \times 10^{-19}\; \rm C$ .

Apply this formula to find the magnitude of the magnetic force on this proton:

$\begin{aligned}F &= q\, v\, b\, \cos\theta \\ &= 1.60 \times 10^{-19}\; \rm C \times 3.2 \times 10^{-7}\; \rm m \cdot s^{-1} \times 1.2 \times 10^{-23}\; \rm T \times \cos\left(90^\circ\right) \\ &\approx 6.1 \times 10^{-49}\; \rm N \end{aligned}$ .

(b)

Apply the right-hand rule to determine to direction of this magnetic force. There are more than one variations of this rule. Here's one of them:

Start by stretching out all five fingers on the right hand in the direction of the motion of this proton (the positive charge, to the north in this question.)Rotate the right arm, so that the imaginary magnetic field lines enter from the back of the right hand and exits from the palm (perpendicularly.)Stretch out the thumb on the right hand so that it points at a $90^\circ$ with the right index finger. The thumb should now point in the direction of the magnetic force on this proton.

Answer from: Quest

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
