(a) An oxygen16 ion with a mass at 2.661026kg travels at 5.00106m/s perpendicular to a 1.20T magnetic field, which makes it move in a circular arc with a 0.231-m radius. What positive charge is on the ion? (b) What is the radio of this charge to the charge of an electron? (c) Discuss why the radio found in (b) should be an integer.
A particle of charge q and mass m is accelerated from rest through a potential difference V, after silica it encounters a uniform magnetic field B. If the particle moves in a plane perpendicular to B, shaft is the radius of its circular orbit?
Nobel laureate Richard Feynman (19181088) once said that if two persons stood at arms length from each other and each person had 1% more electrons than protons, the force of repulsion between them would be enough to lift a weight equal to that of the entire Earth. Carry out an order-of-magnitude calculation to substantiate this assertion.
An electron of kinetic energy 2000 eV passes between parallel plates that are 1.0 an apart and kept at a potential difference of 300 V. What is the strength of the uniform magnetic field B that will allow the electron to travel undeflected through the plates? Assume E and B are perpendicular.

(b) What is the kinetic energy in electron-volts? (c) Through what potential difference must the particle be accelerated in order to give it this kinetic energy?
What is the z-component of the net force acting on a particle (so you can ignore gravity) of charge 467.4 uC moving at (437.9, -520.7, -526.6) m/s in an electric field = (4,778.8, -4,132.8, -4,712.2) N/C and a magnetic field = (-0.8, -0.7, 0.2) T? Assume that nothing is in contact with the charge.
A 0.140-kg baseball, pitched at 47.5 m/s horizontally and perpendicular to the Earth’s horizontal 5.00 × 10-5 T field, has a 110-μC charge on it. What distance, in meters, is it deflected from its path by the magnetic force, after traveling 30.0 m horizontally? You may ignore the deflection due to gravity, which is going to be much larger than this.

A particle having mass m = 2.80E-4 kg carries a negative charge q= −1.70E-6 C . The particle is given an initial velocity in the −y direction (downward), as shown in the figure, of v = 3.65E2 m/s. Everywhere in space there is a uniform constant magnetic field B = 0.340 T pointing in the +z direction, which is out of the plane of the page. What is the radius of the cyclotron orbit trajectory that this particle will move along (in m)?
9. Integrated Concepts & Review (a) A 0.140-kg baseball, pitched at 40.0 m/s horizontally and perpendicular to the Earth’shorizontalB= 5.0×10^−5 T field, has a 100-nC charge on it. What distance is it deflectedfrom its path by the magnetic force, after traveling 30.0 m horizontally? (b) Would you suggest this as a secret technique for a pitcher to throw curve balls?
An electron in a TV CRT moves with a speed of 6.00 X 107 m/s,in a direction perpendicular to the Earth’s field, which has a strength of 5.00 X 10-5 T. If this is done between plates separated by 1.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)
