Ebuah kereta maglev (magnetic levitation train) bermassa 70 ton digunakan untuk transportasi koloni di mars sepanjang amazonis planitia yang terbentang sekitar 1183 km. jika percepatan gravitasi mars gmars = 3,73 m/s², arus yang digunakan sebesar 7 ampere, maka kuat medan magnet minimum yang diperlukan agar kereta tersebut tetap terapung sepanjang perjalanan t

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body
