Calculate the gravitational force between these spheres

AI Thread Summary
The discussion focuses on calculating the gravitational force between two lead spheres using Newton's Law of Universal Gravitation. The spheres have masses of 1.8 kg and 13.9 g, with their centers separated by 5.77 cm. The gravitational constant G is provided as 6.67259 x 10^-11 N m^2/kg^2. There is a correction noted regarding the power of ten in the value of G, indicating it should be -11 instead of +11. The calculation is essential for understanding gravitational interactions in physics experiments.

In introductory physics laboratories, a typical
Cavendish balance for measuring the gravita-
tional constant G uses lead spheres of masses
1.8 kg and 13.9 g whose centers are separated
by 5.77 cm.
Calculate the gravitational force between
these spheres, treating each as a point mass
located at the center of the sphere. Use G =
6.67259 x 10^11 N m^2/kg^2.

Your G is wrong, the power of 10 should be -11.
 
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...
