How Does Charge Location Affect Electric Field Intensity?

AI Thread Summary
The discussion focuses on calculating the net electric field intensity due to point charges located on the x-axis and at the vertices of an equilateral triangle. For the first scenario, the net electric field at -4.0 cm and +4.0 cm is influenced by the charges of 6.4 uC and -9.5 uC, requiring vector addition of their fields. In the second scenario, the electric field at the midpoint between two positive charges (5.00 uC each) and one negative charge (-5.00 uC) in an equilateral triangle is examined. Participants share their approaches to solving these electric field calculations, emphasizing the importance of charge location and distance. Understanding these concepts is crucial for analyzing electric fields in various configurations.

1)

Two point charges lie on the axis. A charge of 6.4 uC is at the origin, and a charge of -9.5 uC is at x = 10cm . What is the net electric field at (a) c = -4.0 cm and at (b) x = +4.0cm ?


2)

The figure shows a system consisting of three charges q1 = +5.00 uC, q2 = +5.00 uC, q3 = -5.00 uC, and at the vertices of an equilateral triangle of side d = 2.85 cm.

Find the magnitude of the electric field at a point halfway between the charges q1 and q2 .

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...
