SUMMARY

The discussion revolves around calculating the mass of an object with a net charge of 18 µC in a uniform electric field of 597 N/C. The object floats in the electric field, indicating that the upward electric force equals the downward gravitational force. By applying the formula for electric force, F = k * q1 * q2 / r^2, and equating it to the gravitational force, the mass can be determined. The solution was successfully reached by balancing these forces.

PREREQUISITES
  • Understanding of electric fields and forces
  • Knowledge of Coulomb's Law
  • Basic principles of gravity and mass
  • Ability to manipulate algebraic equations
NEXT STEPS

Homework Statement



An object with a net charge of 18 µC is placed in a uniform electric field of 597 N/C, directed vertically. What is the mass of the object if it floats in the electric field?

Homework Equations



F=kq1q2/r^2

The Attempt at a Solution


dont understand at all
 
Physics news on Phys.org
Ok, start with the first statement, they said the electric field is directed upwards. So what force is upwards?

Naturally what force will be exerted on the mass downwards?

Now put these two equal to each other.
 
thank you i solved it
