A proton (mass mp), a deuteron (m = 2mp, Q = e), and an alpha particle (m = 4mp, Q = 2e), are accelerated by the same potential difference V and then enter a uniform magnetic field B where they move in circular paths perpendicular to B. Determine the radius of the paths for the deuteron and alpha particle in terms of that for the proton.

Answer with Explanation:

We are given that

Mass of deuteron=

Charge, Q=e

Mass of alpha particle=

Charge,q=2e

Magnetic field=B

Mass of proton=

Let radius of path of proton=r

Using the formula

Velocity of proton=

Centripetal force =Magnetic force

Radius of proton,

Radius of deuteron,

Radius of alpha particle,

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
