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

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
