An electron and a second particle both move in circles perpendicular to a uniformmagnetic field. The mass of the second particle is the same as that of a proton but thecharge of this particle is different from that of a proton. If both of time to go once around their respective circles, determine the charge of thissecond particle. You may use the values:melectron9.1110−31kg, qelectron1.6010−19C, andmproton1.6710−27kg.

The change on the second particle is .

Explanation:

The period of revolution of the particle in the magnetic field is given by the formula as follows :

It is given that the magnetic field is uniform. The mass of the second particle is the same as that of a proton but thecharge of this particle is different from that of a proton.

If both particles take the same amount of time to go once around their respective circles. So,

So, the change on the second particle is .

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

nah.   i'm just sleepy.
