AI Thread Summary
The discussion focuses on understanding the components of the electric charge equation, specifically the origins of the SQRT(3Q) and 2L^2 terms. Participants clarify that these components arise from breaking the electric field vector into its x and y components using trigonometric functions. The cosine and sine values for a 30-degree angle, specifically cos(30) = SQRT(3)/2 and sin(30) = 1/2, are essential for this breakdown. The lack of a strong background in trigonometry is acknowledged as a challenge for some participants. Overall, the conversation emphasizes the importance of trigonometric principles in understanding electric field calculations.
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...
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
$$T + f_f - N_w = Ma$$

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is
The second part of the problem is exactly why you get this affect.
