An x-ray tube operated at DC pd of 40KV produces heat at the target at the rate of 720W. assuming 0.5% of the energy of the incident electrons is converted into x radiation. calculate:
(1) the number of electrons persecond stricking the target
(2) the velocity of the incident electrons. (Assuming charge to mass ratio of electron to be1.8*10^11C/Kg)

The tube in a medical research X-ray unit uses lead (Z=82) as it's target. 1) Use the Bohr model to estimate the minimum kinetic energy electrons must have to in order for Kα X-rays to just appear in the X-ray spectrum of the tube. Ee = 2) Assuming the electrons are accelerated from rest through a voltage, V, what is the minimum voltage necessary to produce the Kα X-rays?

Finding the charge to mass (e/m) ratio of the electron Often in physics, we look for ways to find fundamental physical constants. From the set-up demonstrated in class, we are able to find a monumental combination of two physical constants-the charge of an electron (e) and the mass of an electron (m). Since the charge of an electron (e) is well known through other experiments, we will use the ratio of charge to mass to find the mass of an...
