g What is the separation between their paths in meters when they hit a target after traversing a semicircle

vm/B•q

Explanation:

The charge to mass ratio of any given particle, can be determined by using the formula

q/m = E/BB•R,

From the aforelisted formula,

Both E and B are the fields in the velocity selector.

B• is the magnetic field used to separate particles

R is the radius of the path of the particle.

Now, we rearrange by making R the subject of the formula, so that

R = Em/BB•q

In trying to find the velocity of the particles coming out of the velocity selector, we realize that

v = E/B, and when we substitute for this in the previous equation, we have

R = vm/B•q
