Two protons are released from rest 15 mm apart. (A) describe the subsequent motion after they are released.(B) how fast are the protons moving when they are a great distance apart
Give the answer if the initial separation is 14 mm
In a television picture tube, electrons strike the screen after being accelerated from rest through a potential difference of 17000 V. The speeds of the electrons are quite large, and for accurate calculations of the speeds, the effects of special relativity must be taken into account. Ignoring such effects, find the electron speed just before the electron strikes the screen.
In large CRT televisions, electrons are accelerated from rest by a potential difference of 23.88 kV
and shot onto a phosphorescent screen to produce an image. What is the speed of the electrons
