Two identical circular, wire loops 48.0 cm in diameter each carry a current of 4.50 a in the same direction. these loops are parallel to each other and are 30.0 cm apart. line ab is normal to the plane of the loops and passes through their centers. a proton is fired at 2600 m/s perpendicular to line ab from a point midway between the centers of the loops. part a find the magnitude of the magnetic force these loops exert on the proton just after it is fired. ff = nothing n

Explanation:

It is given that,

Diameter of loops, d = 48 cm = 0.48 m

Radius of the loop, r = 0.24 m

Current carried in the loop, I = 4.5 A

Distance between loops, x = 30 cm = 0.3 m

Speed of the proton, v = 2600 m/s

We know that the magnetic field at the midway of the coils is given by :

Let F is the magnetic force these loops exert on the proton just after it is fired. It is given by :

So, the magnetic force these loops exert on the proton is . Hence, this is the required solution.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
