Calculate charge and capacitance

AI Thread Summary
Three capacitors, C1 (4.5 mF), C2 (7.5 mF), and C3 (10 mF), are connected in series to a 150V DC supply. To find the total capacitance, the formula for capacitors in series, 1/C_total = 1/C1 + 1/C2 + 1/C3, is used. Each capacitor will have the same charge, which can be calculated using Q = C_total * V. The potential difference across capacitor C3 can be determined using V = Q/C3. Understanding these calculations is crucial for mastering this aspect of physics.

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...
