Question

1.In a pith ball experiment, the two pith balls are at rest. The magnitude of the tension in each string is |T| = 0.55 N, and the angle between each string and a vertical line is θ = 27.33°. What are the values for the magnitudes of electrostatic force, Fq, and the gravitational force, Fg?

2.One object has a charge of +5.0 × 10−6 C, and a second object has a charge of +2.0 × 10−6 C. The objects are 0.5 meters apart. What is the electrostatic force between them?

Answer 1

Indicate your <I>specific</I> subject in the "School Subject" box, so those with expertise in the area will respond to the question.

Answer 2

For first question make a FBD diagram and then solve components.

For the second question remember the basics F= kq1q2/(r)^2
