1. n an x-ray tube, electrons are accelerated in a uniform electric field and then strike a metal target. Suppose an electron starting from rest is accelerated in a uniform electric field directed horizontally and having a magnitude of 2900 N/C. The electric field covers a region of space 12.5 cm wide.

A. What is the speed of the electron when it strikes the target?

B. How far does it fall under the influence of gravity during its flight?   

A) find force due to electric field using charge of an electron.

Find the acceleration using mass of an electron

Use the given distance to find the final speed

B) We need the time in flight:

Now find the distance fell due to gravity:

It fell 2.42*10-15m

2 Two large parallel plates are separated by 0.90cm and carry uniform charge densities equal in magnitude and opposite in sign. A proton is between the plates and has an acceleration of magnitude 1.40
