The strength of the earth’s magnetic field b at the equator is approximately equal to 5 × 10−5 t. the force on a charge q moving in a direction perpendicular to a magnetic field is given by f = q v b, where v is the speed of the particle. the direction of the force is given by the right-hand rule. suppose you rub a balloon in your hair and your head acquires a static charge of 9 × 10−9 c. if you are at the equator and driving west at a speed of 90 m/s, what is the strength of the magnetic force on your head due to the earth’s magnetic field? answer in units of n. what is the direction of that magnetic force?
