Now Safiya and Amy try a homework problem. Consider an electron moving with a speed of 8.70 106 m/s at right angles to a constant magnetic field, with B = 1.7 T. What is the radius of the circular path of the electron? r = m

Radius of circular path will be

Explanation:

Mass of electron

Charge on electron

Speed of electron is given

Magnetic field is given B = 1.7 T

We have to find the radius of the circular path

Radius of circular path is equal to , here m is mass v is velocity q is charge and B is magnetic field

So

So radius of circular path will be

b) 10 minutes

girls stopped for 10 minutes.

c) up is the direction the magnetic force is acting on the charge.
