Answer:
6700 m/s
Explanation:
The magnetic field due to a solenoid is given by B = μ₀in where i = current, n = number of turns per unit length = N/l and μ₀ = 4π × 10⁻⁷ H/m
Let B₁ be the magnetic field for the outer solenoid. For this solenoid, i = 5.33 A, n = N/l = 539 turns/0.215 m since l = 21.5 cm = 0.215 m
B₁ = 5.33 A × 539 turns/0.215 m × 4π × 10⁻⁷ H/m = 0.017 T
Let B₂ be the magnetic field for the inner solenoid. For this solenoid, i = 1.95 A, n = N/l = 395 turns/0.181 m since l = 18.1 cm = 0.181 m
B₂ = 1.95 A × 395 turns/0.181 m × 4π × 10⁻⁷ H/m = 0.0053 T
Since the magnetic fields are in opposite direction, the net magnetic field is B = B₁ - B₂ = 0.017 T - 0.0053 T = 0.0117 T.
This magnetic field produces a magnetic force on the proton which is equal to the centripetal force on the proton. So at r = 5.95 mm
Bev = mv²/r
v = Ber/m = 0.0117 T × 1.6 × 10 ⁻¹⁹ C × 5.95 × 10⁻³ m/1.67 10⁻²⁷ kg = 6669.7 m/s ≅ 6700 m/s
False. The force comes first as in tapping or hitting a balloon. Then comes the motion and that might be the balloon dating in the direction it was shoved.
The hottest would be the O type and the coolest is M
Gravity is the cause of . . .
-- star formation,
-- planet formation,
-- orbits.
So without gravity, there pretty much wouldn't be any solar or any system.
