Aphysicist performing a sensitive measurement wants to limit the magnetic force on a moving charge in her equipment to less than 1.00 x 10 -12 n. what is the greatest the charge can be if it moves at a maximum speed of 30.0 m/s in the earth’s field? you may assume the earth’s magnetic field is 5.00 x 10 -5 t.

Maximum charge will be

Explanation:

We have given force ion the moving charge

Maximum speed of the moving charge v = 30 m /sec

Magnetic field

We have to fond the charge

Force on moving charge is given by

So

Maximum charge will be

hello there!

your answer is a “generator”

a generator does not create energy but instead it transforms it.

it’s basically a motor working in reverse.
