object A might be charged or uncharged
Here Object A can be attracted to object in two cases ,when object A has an opposite sign of charge to that of charge B and
when object A is uncharged i.e neutral will attract charge B ,inducing a charge on it's surface of A

Object 1 is positively charged. Object 2 is neutral. Explain in detail WHY objects and 2 are attracted to each other by an electrostatic force. (I thought only oppositely charged objects are attracted to each other!) Use clear words and diagrams.

2. A positively charged object is placed close to a conducting object attached to an insulating glass pedestal (a). After the opposite side of the conductor is grounded for a short time interval (b), the conductor becomes negatively charged (c). Based on this information, we can conclude that within the conductor A. both positive and negative charges move freely. B. only negative charges move freely. C. only positive charges move freely. D. We can't really conclude anything.

Suppose Point B is 7.12 m from this charged object. What is the magnitude (we sometimes also say strength) of the electric field at Point B due to the charged point object? Suppose Point A is 3.38 m from this charged object. What is the magnitude (we sometimes also say strength) of the electric field at Point A due to the charged point object?

4. When a solid object is suspended from a spring scale in air the scale reads 21.7N. The object is then completely submerged in water and the spring scale reads 16.6N. Draw a free-body diagram for the object suspended from the scale in air. You may ignore the very small buoyant force from the air. Using a Newton's 2 nd law equation for the vertical direction on your FBD determine the mass of the object. Draw a free-body diagram for...

If ?(?) = 0.6, ?(?) = 0.2, and ?(?|?) = 0.2, what can we conclude about the relationship between A and B? If ?(?) = 0.23,?(?|?) = 0.56, what can we conclude about the relationship between A and B? If ?(?) = 1 3 , and ?(? and ?) = 0, what, if anything, can we conclude about the relationship between C and D?
