    Electrons Pressure
AI Thread Summary
Electrons striking a television screen at a speed of 7.31 x 10^7 m/s create a glowing effect by transferring momentum upon impact. Each electron has a mass of 9.11 x 10^-31 kg, and approximately 7.97 x 10^16 electrons hit the screen every second across an area of 2.15 x 10^-7 m^2. To calculate the pressure exerted by the electrons, one must determine the total force from the momentum change of the electrons and then divide by the area. The relationship between force, pressure, and area is essential for solving this problem. Understanding these principles allows for the calculation of the pressure exerted on the screen by the electron stream.

In a TV, electrons with a speed of 7.31 x 107 m/s strike the screen from behind, causing it to glow. The electrons come to a halt after striking the screen. Each electron has a mass of 9.11 x 10-31 kg, and there are 7.97 x 1016 electrons per second hitting the screen over an area of 2.15 x 10-7 m2. What is the pressure that the electrons exert on the screen?

Hi, can anyone help me please? I really don't know how to start this question. It confuses me a lot.
 
Physics news on Phys.org
Force is F=m*a. And Pressure is F/A where A is area.

Force is also dP/dt where P is momentum mv.

Now you know what the rate of momentum the screen is absorbing by the m*v of the total number of electrons in the stream of electrons in a second. And you know the area over which they want the Pressure.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
