Answer:
The velocity is 31.25 m/s and direction is toward west.
Explanation:
Given that,
Distance ![h= 1790 km = 1.790\times10^{6}\ m](https://tex.z-dn.net/?f=h%3D%201790%20km%20%3D%201.790%5Ctimes10%5E%7B6%7D%5C%20m)
Magnetic field ![B=4\times10^{-8}\ T](https://tex.z-dn.net/?f=B%3D4%5Ctimes10%5E%7B-8%7D%5C%20T)
Mass of proton ![m=1.673\times10^{-21}\ Kg](https://tex.z-dn.net/?f=m%3D1.673%5Ctimes10%5E%7B-21%7D%5C%20Kg)
Radius of earth ![R =6.38\times10^{6}\ m](https://tex.z-dn.net/?f=R%20%3D6.38%5Ctimes10%5E%7B6%7D%5C%20m)
Radius of orbit ![r=R+h](https://tex.z-dn.net/?f=r%3DR%2Bh)
![r=6.38\times10^{6}+1.790\times10^{6}](https://tex.z-dn.net/?f=r%3D6.38%5Ctimes10%5E%7B6%7D%2B1.790%5Ctimes10%5E%7B6%7D)
![r=8170000\ m](https://tex.z-dn.net/?f=r%3D8170000%5C%20m)
We need to calculate the speed
Using formula of magnetic field
![Bvq=\dfrac{mv^2}{r}](https://tex.z-dn.net/?f=Bvq%3D%5Cdfrac%7Bmv%5E2%7D%7Br%7D)
![v=\dfrac{Bqr}{m}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7BBqr%7D%7Bm%7D)
Put the value into the formula
![v=\dfrac{4\times10^{-8}\times1.6\times10^{-19}\times8170000}{1.673\times10^{-21}}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B4%5Ctimes10%5E%7B-8%7D%5Ctimes1.6%5Ctimes10%5E%7B-19%7D%5Ctimes8170000%7D%7B1.673%5Ctimes10%5E%7B-21%7D%7D)
![v=31.25\ m/s](https://tex.z-dn.net/?f=v%3D31.25%5C%20m%2Fs)
Hence, The velocity is 31.25 m/s and direction is toward west.
Answer:
because there is external pressure is less in the height.
