Auniform magnetic field of 0.50 t is directed along the positive x axis. a proton moving with a speed of 60 km s enters this field. the helical path followed by the proton shown has a pitch of 5.0 mm. determine the angle between the magnetic field and the velocity of the proton.

Explanation:

It is given that,

Magnetic field, B = 0.5 T

Speed of the proton, v = 60 km/s = 60000 m/s

The helical path followed by the proton shown has a pitch of 5.0 mm, p = 0.005 m

We need to find the  angle between the magnetic field and the velocity of the proton. The pitch of the helix is the product of parallel component of velocity and time period. Mathematically, it is given by :

So, the angle between the magnetic field and the velocity of the proton is 50.58 degrees. Hence, this is the required solution.

as technology advances, new experiments often expose problems in accepted theories. c

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
