Pull a rectangular loop through a magnetic field

AI Thread Summary
The discussion revolves around solving a physics problem related to a rectangular loop moving through a magnetic field. The key equations involved are E = vB and F = qVB. The poster is confused about the correctness of multiple-choice answers regarding the behavior of the loop in the magnetic field, specifically questioning the validity of options 1, 2, and 3. Clarification is provided that option 1 is correct, option 3 is incorrect, and option 2 requires consideration of the current's direction using the right-hand rule. Understanding the right-hand rule is essential for determining the magnetic field direction for each segment of the loop.

Homework Equations



E=vB
F=qVB

The Attempt at a Solution



My question is the last part "which of the following are true". I've tried these choices and all were wrong:

(1, 2, 3)
(1, 2)
(2)
(1, 3)

I really am confused. I swear 1 is right. Right? 2 seems to be right, and 3 should be wrong. But right now I'm confused and don't know what is what. Any help is much appreciated.

Yes, 1 is indeed right, and 3 should be wrong. For 2, think about which direction the current is flowing in. Use the right-hand rule to find out the direction of the magnetic for all segments of the loop.
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
