B. X-RAY TUBE Target Dentists use X-ray tube to image their patients ' teeth and bones. As shown on the figure on the right, a large Electron Sarce current flows through the electron source , causing electrons to be ejected from the electron source . The electrons are then accelerated toward the target by the electric field. When they strike the target, X-rays are produced Problem Solving DEP Figure 2. An x-ray tube . Illustrated by Marc A Directions . Read each statement then perform the Christion Perez tasks that follow . Write your computation in the space provided and box your final answer 37 Situation : The X-ray tubes that generate X-rays contain an electron source separated by about 10 cm from a metallic target. The electrons accelerate from the source to the target by a uniform electric field with a magnitude of about 100, 000 N/C (a) Compute the potential difference between the electron source and the metallic target. (b) Calculate the kinetic energy of the electrons when they reach the target, assuming that the electrons start from rest
