Acharged particle beam (shot horizontally) moves into a region where there is a constant magnetic field of magnitude 0.00348 t that points straight down. the charged particles in the beam move in a circular path of radius 1.17 cm. if the charged particles in the beam were accelerated through a potential difference of 110 v, determine the charge to mass ratio of the charged particles in the beam. answer in units of c/kg.

Explanation:

It is given that,

Magnetic field, B = 0.00348 T

Radius of circular path, r = 1.17 cm = 0.0117 m

If the charged particles in the beam were accelerated through a potential difference of 110 V, V = 110 V

Let q is the charge and m is the mass.

The centripetal force is balanced by the magnetic force as :

...........(1)

Also,

Put the value of v in equation (1) as :

So, the charge to mass ratio of the charged particles in the beam is . Hence, this is the required solution.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
