At a certain location, the horizontal component of the earth's magnetic field is 2.7 × 10-5 T, due north. A proton moves eastward with just the right speed, so the magnetic force on it balances its weight. Find the speed of the proton.

Therefore the velocity of the proton is m/s towards east.

Explanation:

The mass of proton is m= kg.

q= C is  the magnitude of the charge of a proton.

The earth's magnetic field is B= T toward north.

Let v be the velocity of the proton towards east.

The angle between the velocity of proton towards east and magnetic field towards north is .

We know that,

Now putting the all values

    m/s

Therefore the velocity of the proton is m/s towards east.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
