Question

A point charge with a charge q1 = 2.10 μC is held stationary at the origin. A second point charge with a charge q2 = -4.20 μC moves from the point x= 0.140 m , y= 0 to the point x= 0.250 m , y= 0.250 m

Answer 1

The question involves electric fields and forces between point charges according to Coulomb's law, typical in high school physics.

Step-by-step explanation:

The question is about the movement of a point charge in an electric field created by another fixed point charge. Specifically, it focuses on finding the electric field, force on charges, and potential energy changes within systems of point charges. Such problems typically involve the concepts of Coulomb's law, the superposition principle for electric fields, and electric potential energy calculations. These questions are addressed in high school and undergraduate physics courses, particularly within a unit on electrostatics.
