Electric dipole moment question

AI Thread Summary
An electric dipole consists of two equal and opposite charges separated by a distance. The discussion focuses on calculating the electric field "E" at a point "P" when both charges are assumed to be positive, under the condition that the distance to point "P" (X) is much greater than the separation distance (d) between the charges. Participants express confusion regarding the assumption of both charges being positive, as this contradicts the standard definition of a dipole. Clarification on the nature of electric dipoles and the implications of the assignment is sought. The conversation highlights the complexities involved in understanding electric dipole moments in physics.

1. In an electric dipole moment, assume that both charges are positive and find the electric field "E" at point "P", assuming X>>d, where "d" is the distance between the two charges and "X" is the distance of point "P" from the center of the dipole.

I have thought a lot about it but I am very much confused. Any help will be greatly appreciated.

Thanks

Okay, well let's start with the definition of an electric dipole - what is it?

"a pair of equal and opposite electric charges or magnetic poles separated by a small distance".

I was also thinking that we cannot assume that both charges are positive, but my teacher gave me this question as an assignment. I thought that may be there is a solution for this. So confused!
 

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...
