Help Needed: Calculating Mass/Charge Ratio & Carbon Atom Count

AI Thread Summary
To calculate the mass-to-charge ratio of a toner particle in a photocopier, additional information is needed beyond the electric field strength. The force required to attract the toner particle must be ten times its weight, which relates to its mass and charge. If the toner particles are made of carbon, it is established that there are approximately 6 x 10^23 carbon atoms for each excess electron on a toner particle. The discussion emphasizes the need for more data to complete the mass-to-charge ratio calculation. Understanding these relationships is crucial for analyzing the behavior of toner in photocopiers.

Hi I am just having trouble figuring out this question. If someone can help me out it would be greatly appreciated

The imaging drum of a photocopier is positively charged to attract negatively charged particles. Near the surface of the drum, its electric field has a magnitude of 1.40 * 10^5 N/C. A toner particle is to be attracted to the drum with a force that is ten times the weight of the particle.

What is the ratio of the mass of a toner particle to the magnitude of its net charge?

If the toner particles are made of carbon, how many carbom atoms are there for each excess electron on a toner particle?

The ratio of the mass of a toner particle to the magnitude of its net charge is not possible to calculate without additional information. If the toner particles are made of carbon, there would be 6 x 10^23 carbon atoms for each excess electron on a toner particle.
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
