How do i sketch the equipotential lines ?

AI Thread Summary
To sketch equipotential lines for an isolated negatively charged particle, recognize that these lines are always perpendicular to electric field lines. Electric field lines originate from positive charges and terminate at negative charges, meaning they will extend radially inward toward the negatively charged particle from infinity. The equipotential lines will be circular and centered around the particle, indicating regions of equal electric potential. Understanding these relationships is crucial for accurately representing electric fields and potentials in diagrams. This knowledge is essential for studying electrostatics and related concepts.

How can i sketch the equipotential lines for an isolated negatively charged particule?
 
Physics news on Phys.org
the equipotential lines are perpendicular to the electric field lines.
 
and in which way are oriented the electriv field lines ?
 
Your textbook should have rules for drawing electric field lines or something like that. It says that the lines must begin on a positive charge and terminate on a negative charge. So that means that since you have one negatively charged particle, the lines will begin infinitely far away and will be directed radially inwards towards the particle. That is, the tail of the arrow is at infinity and the point of the arrow is pointing towards the particle.
 
thanks pal ur the best :)
 

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...
