AI Thread Summary
The discussion revolves around calculating the angular magnification of a simple magnifier with a focal length of 50 cm when the image is formed at the near point of 25 cm. Two equations are provided for calculating magnification: m = N/d and m = 1 + N/f. The user initially expresses confusion about which equation to use for the problem. Ultimately, the user finds the solution to their query independently. The thread highlights the importance of understanding the application of magnification formulas in optics.

Homework Statement


A lens having a focal length 50 cm is used as
a simple magnifier.

What is the angular magnification obtained
when the image is formed at the normal near
point (25 cm)?


Homework Equations



1) m = N/d, where d is distance of object

2) m = 1 + N/f

I don't really get what do they want as the answer.

Also, there are two equations, which one do I use?

THanks! :)

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...
