Physics electrostatics question

AI Thread Summary
The dielectric constant of a medium is affected by temperature, particularly in materials with permanent dipoles. Although the formula K=ε/ε0 does not explicitly include temperature, heat influences orientational polarization, leading to variations in the dielectric constant. Resources such as the Cambridge University site provide detailed explanations and visual aids on this topic. Understanding these effects is crucial for accurate applications in electrostatics. Therefore, temperature does play a significant role in the behavior of dielectrics.

i just can't seem to figure out what is the effect of temprature on dielectric constant of a medium. since, K=ε/ε0, therefore according to me there is no effect of temperature as temperature is not in the formula. Please help.

hi priyanshm! welcome to pf! :smile:

from the cambridge university site http://www.doitpoms.ac.uk/tlplib/dielectrics/temperature.php …
For materials that possesses permanent dipoles, there is a significant variation of the dielectric constant with temperature.
This is due to the effect of heat on orientational polarisation.

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'

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...
