    Particle Track
AI Thread Summary
The discussion focuses on two questions regarding particle tracks in a room divided into four quadrants: Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR). For the first question, the correct answer indicating opposite B field directions in TL and TR is identified as B, while for the second question, the correct answer indicating the same B field direction in TL and BL is A. The initial answers provided by the poster were incorrect, leading to the request for clarification. The importance of focusing on the relevant trajectories for each question is emphasized. Clear understanding of quadrant relationships is crucial for solving these particle track questions.

Homework Statement


So there are 2 questions i need help with.
1. Divide the room (for the rest of this valdation) into four (4) quadrants labeled Top Left (TL), Top Right (TR), Bottom Left (BL), and Bottom Right (BR). Which of the four particle tracks indicates that the B field in the TL and TR quadrants are in the opposite direction?
2. Which of the four particle tracks indicates that the B field in the TL and BL quadrants are in the same direction?

Homework Equations


no equations needed



The Attempt at a Solution


for number 1, i thought the answer would be C, and two i thought the answer would be D. But i got both answers wrong. I was wondering if someone could help me on these 2 questions.
Thanks.

Problem 1 asks about "top left" and "top right" so only a trajectory that stays in the top half is relevant. Problem 2 talks about the "top left" and "lower left" so only a trajectory that stays in the left half is relevant.
 
SO could you say that for problem one would have to be B, and for problem 2 the answer would have to be A?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
