A long straight wire suspended in the air carries a conventional current of 8.2 amperes in the ?x direction as shown in the figure (the wire runs along the x axis). At a particular instant an electron at location <0,-0.003,0>m has velocity< -1.5e5,1.8e5,0>m/s.
(a) What is the (vector) magnetic field due to the wire at the location of the electron?
(b) What is the (vector) magnetic force on the electron due to the current in the wire?
(c) If the moving particle were a proton instead of an electron, what would be the (vector) magnetic force on the proton?
A cord is wrapped around the rim of a solid uniform wheel 0.300 in radius and of mass 7.80 . A steady horizontal pull of 40.0 to the right is exerted on cord, pulling it off tangentially from the wheel. The wheel is mounted on frictionless bearing..
Evaluate (a) the acceleration of each object, (b) the tension in the string, and (c) the coefficient of kinetic friction between m2 and the incline.
What is the wavelength of an 102.1 FM radio station and What is the wavelength of an 1310 AM radio station
The ground state energy of a harmonically oscillating electron is 1.24 eV. How much energy should be added to the electron to move it to the second excited state.
To move a large crate of mass 30.05 kg across a rough floor, you push on it with a force at an angle of = 22.8° below the horizontal. Compute the acceleration of the crate if the applied force is 382 N and coefficient of kinetic friction is 0.486.
In the August 1992 space shuttle fight, only 250 m of the conducting tether could be let out. What was the angle between the shuttle's velocity and the Earth's field, assuming the conductor was perpendicular to the field
An electron of kinetic energy 1.58 keV circles in a plane perpendicular to a uniform magnetic field. The orbit radius is 33.0 cm. Find the circling frequency (in Hz)
Two kilomoles of a monatomic ideal gas are at a temp of 300K. The gas expands reversibly and isothermally twice its original volume. Calculate the work done by the gas. (Note that for an ideal gas U is proportional to T, so the change of U = 0 in ..
find out kinetic energy of ball at the highest point of motion.
