A magnetic field of 0.2 T is acting in the south-west direction. (You can ignore the earth’s magnetic field.) A particle of mass 0.06 kg and charge 0.6 C is travelling in the west direction with unknown speed. It is seen to move vertically upwards with an acceleration of 8 m/s2. a) What is the total force acting on this particle in the (upwards) vertical direction? b) What is the magnitude of the magnetic force acting on this particle? (You can assume that the acceleration due to the earth’s gravity is 10 m/s2 .) c) What is speed of the particle?

A current-carrying wire is in a B-field and experiences a magnetic force (FB>0). The magnetic force vector is shown below. Choose all the arrows that could represent the current direction. Magnetic force Current direction 45° 45° 45* 45° 45° 40 45° 45°

A cyclotron is a device for accelerating charged particles to high speed as they follow an expanding spiral-like path (See LHC, NSRRC, or an MRI machine). The charged particles are subjected to both an electric field and a magnetic field. One of these fields increases the speed of the charged particles, and the other field causes them to follow a curved path. Which one does the latter? The magnetic field, since it exerts a force to the moving charge perpendicular to the charges' direction of motion. The electric field, since it exerts a force that accelerates the particle in the curved path of the facility. Not necessarily only one. Both contributes to the particles' curving of path as both exert force perpendicular to their velocity's direction. None of them. The curving of charges occur due to the design of the facility/device.

A particle with unknown properties moves into a region of space containing both a uniform electric field and a uniform magnetic field, as shown below. The particle begins to deviate upwards from its original trajectory. How do the magnitudes of the two forces compare? OB The electric force is stronger than the magnetic force The magnetic force is stronger than the electric force А. В. С. The electric force and the magnetic forceare equal in magnitude (but nonzero) The electric force and the magnetic force are both exactly zero Nothing can be determined without additional information D. Е.

QUESTION 6 Two long current carrying wires, I and I2, are separated by 2 mm and both carry a current of 8 A. What is the x-component of the magnetic force in newtons on a one meter length of one of the top wire?

When a charged particle moves perpendicularly to the direction of a uniform magnetic field, the direction of the magnetic force is perpendicular to both the direction of the magnetic field and the direction of the velocity of the charged particle.  Accordingly, the charge begins to move in a circular path.  Since the direction of the magnetic force is toward the center of the circular path the charged particle moves along, the magnetic force is a centripetal force (recall centripetal forces from chapter 5 of the text, covered in PHY 2010).  A schematic of such motion is shown below.  The "X"s represent the magnetic field that is directed into the plane of this screen.  The direction of velocity and magnetic force lie within the plane of this screen and are at right angles to one another, as shown below.   If a charge of magnitude 7.45x10-17C, with speed 4.66x106 m/s, and mass 7.12x10-25kg moves within the magnetic field of magnitude 3.96x10-2T, what is the resulting radius of the path…

Let v the velocity of a particle in a constant magnetic field B. We wish to decompose v into v = v⊥ + vk where v⊥ is perpendicular to the magnetic field and vk is parallel to it. Derive vector expressions for v⊥ and vk in terms of v and B.
