What is the magnitude of the charge on each particles

AI Thread Summary
The discussion focuses on calculating the magnitude of charge on two particles with equal and opposite charges, placed 14.8 cm apart. Given the mass of the first particle as 41.0 g and its acceleration of 1.40 m/s², along with the second particle's mass of 54.7 g and acceleration of 1.05 m/s², the relationship between mass and acceleration is emphasized. The formula used, q = sqrt(1/k d² m1 a1), is questioned for accuracy, as the calculated charge of 1.2E-5 C is deemed incorrect. The correct approach involves applying Newton's second law, where m1*a1 equals m2*a2, reflecting the forces acting on both particles. Clarifying the calculations and ensuring the correct application of formulas is essential for accurate results.

In the previous problem, what is the magnitude of the charge on each particle?

the previous problem was
Two point-like particles are placed 14.8 cm apart and are given equal and opposite charge. The first particle, of mass 41.0 g, has an initial acceleration of 1.40 m/s2 towards the second particle. What is the mass of the second particle if its initial acceleration towards the first is 1.05 m/s2?
and the answer to that was 54.7g

so i just don't know what I am doing wrong.

so i did this
q= sqrt(1/k d^2m1a1
my answer came to 1.2E-5C but it isn't right. I don't see where I went wrong

You can just right
m1*a1 = m2*a2 because both the charge experience equal and opposite force of attraction.

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.
