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 6 × 10−9 c. if you are at the equator and driving west at a speed of 80 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.

Explanation:

Since the Earth's magnetic field is perpendicular to your direction of motion, the strength of the magnetic force exerted on your head is given by:

where:

is the charge on your head

is the speed at which you are moving

is the strength of the magnetic field of the Earth

By substituting these numbers into the equation, we find the strength of the magnetic force:

i don't understand. explain it clearly

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
