Answer 1

Answer on Question #50910, Physics, Astronomy

2. b) If the pressure in the solar atmosphere is $10^{4}\mathrm{Pa}$, calculate the strength of the magnetic field required to balance it (pressure).

Answer:

According to Newton's second law required force is given by Eq. (1)

$$F _ {H} \approx 4 \pi R _ {\odot} ^ {2} p = 4 \pi \left(695800 \cdot 10 ^ {3}\right) ^ {2} 10 ^ {4} \approx 6.08 \cdot 10 ^ {22} H$$

where $R_{\odot} = 695800\mathrm{km}$ is the radius of the Sun.
