Question

2. An electron in a CRT is accelerated through apotentialdifference of 10kV, and then passes through 2.0 cm wideregion ofuniform magnetic field into the page.

1. What is the speed of the electron as it enters themagneticfield region?
2. What magnetic field strength will deflect the electronby10^o
3. If the same magnetic field found in part (b) is used andaproton instead is traveling in the magnetic field region. Willtheangle of deflection be:

_________Greater

_________Smaller

_________ The same.
