AI Thread Summary
The discussion focuses on calculating the net force and electric field acting on charge 1 in a given charge distribution. Participants emphasize the use of the electrostatic force equation, F = (k)(Q1)(Q2)/d^2, to determine the force. There is a reminder that the force is a vector quantity, indicating the importance of direction in calculations. Some users point out that additional information is needed to complete the calculations accurately. The conversation highlights the need for careful consideration of both magnitude and direction when analyzing electric forces.

You have the equation for electrostatic force. Apply it to the given setup.
 
F = (2)(+2 x 10^-5)(-3 x 10^-5)
Is that right?

Some things are missing from that equation. Don't forget that force is a vector.
 

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...
