What is the magnitude of the charge on each particles

Click For Summary
SUMMARY

The discussion centers on calculating the magnitude of the charge on two point-like particles with equal and opposite charges, positioned 14.8 cm apart. Given the mass of the first particle as 41.0 g and its acceleration of 1.40 m/s² towards the second particle, the mass of the second particle is determined to be 54.7 g with an acceleration of 1.05 m/s² towards the first. The incorrect calculation of charge using the formula q = sqrt(1/k d² m1 a1) resulted in a value of 1.2E-5 C, which was identified as erroneous. The correct approach involves applying Newton's second law, where m1*a1 = m2*a2, due to the equal and opposite forces acting on the charges.

PREREQUISITES
  • Understanding of Coulomb's Law and electrostatic forces
  • Familiarity with Newton's second law of motion
  • Basic knowledge of particle physics and charge interactions
  • Ability to manipulate equations involving mass, acceleration, and force
NEXT STEPS
  • Review Coulomb's Law for calculating forces between charged particles
  • Study Newton's laws of motion in the context of particle interactions
  • Explore the concept of electric charge and its quantization
  • Practice problems involving forces and accelerations of multiple particles
USEFUL FOR

Students studying physics, particularly those focusing on electrostatics and dynamics of charged particles, as well as educators seeking to clarify concepts related to forces and accelerations in particle systems.

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.
