Electrostatics - Compute the electric charge

Click For Summary
SUMMARY

The discussion focuses on calculating the electric charges of three point charges, q1, q2, and q3, placed at the vertices of a triangle. Charge q1 has 4.5 x 1013 extra electrons, q2 has 9.0 x 1013 extra electrons, and q3 has 9.0 x 1013 electrons removed. The participants emphasize the importance of knowing the charge of a single electron, which is approximately -1.6 x 10-19 coulombs, to compute the total electric charges accurately.

PREREQUISITES
  • Understanding of electric charge and its quantization
  • Familiarity with the concept of point charges in electrostatics
  • Knowledge of the formula V = u/q for electric potential
  • Basic arithmetic skills for calculations involving large numbers
NEXT STEPS
  • Research the charge of an electron and its role in calculating electric charge

Homework Statement


three point charges q1,q2&q3 are place at the vertices of triangle as shown in the diagram charge q1 has been given 4.5 X 10^13 extra electrons, charge q2 given 9.0 X10^13 extra electrons and q3 has had 9.0 X 10^13 electrons taken from it. Calculate the electric charge of q1,q2,&q3?


Homework Equations


no,sorry..

3. The Attempt at a Solution [
1stly i use the formula V=u/q to find the charge but it doesn't work,so I'm stuck with it!

What's the charge per electron? (Look it up.)
