A charged particle is injected at 265 m/s into a 0.0891 ‑T uniform magnetic field perpendicularly to the field. The diameter of its orbit is measured and found to be 0.0383 m. What is the charge–to–mass ratio of this particle?

Charge to mass ratio of particle is 155309.98

Explanation:

We have given velocity of charged particle v = 265 m/sec

Magnetic field B = 0.0891 T

Diameter of the orbit is given d = 0.0383 m

So radius of the orbit

We have to find the charge to mass ratio of particle

Radius of the orbit is equal to

0.0191=\frac{m\times 265}{q\times 0.0891}

So charge to mass ratio of particle is 155309.98

spectral lines lyman is one set

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
