Amass spectrograph is operated with deuterons, which have a charge of +e and a mass of 3.34 x 10-27 kg. deuterons emerge from the source, which is grounded with negligible velocity. the velocity of the deuterons as they pass through the accelerator grid is 8.0 x 105 m/s. a uniform magnetic field of magnitude b = 0.20 t, directed out of the plane, is present at the right of the grid. in the figure, the deuterons are in circular orbit in the magnetic field. the radius of the orbit and the initial sense of deflection are closest to:

0.0835 m

Explanation:

The magnetic force exerted on the deuteron is equal to the centripetal force that keeps it in circular motion:

where

is the charge

is the speed of the deuteron

is the magnetic field strength

is the mass of the deuteron

r is the radius of the orbit

re-arranging the equation, we find:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff
