... P4: Find the magnetic force on a proton coming towards our planet at a speed of 4x105m/s if the magnetic field of the Earth is 1.5x10-5T at that point and it is perpendicular to the velocity of the proton (as shown in the figure). Answer with magnitude and indicate the direction of the force in the ...
