The diagram shows the arrangement of three small uniformally charged spheres, A,B and C. The arrow indicate the direction of the electrostatic forces acting between the spheres (for example, the left arrow on sphere A indicates the electronstatic force on sphere A due to sphere B). At least two of the spheres are positively charged. Which sphere, if any, could be negatively charged?

In two cases, two identical conducting sphere are given equal charges, in one case of the same type whereas in another case of opposite type. The distance between the spheres is not large comparing with the diameter. Let F1 and F2 be the magnitudes of the force of interaction between the spheres, as shown, then

A positively charged rod is brought near to a non-conducting object. The rod is attracted to the object. From this observation. We can’t predict whether the object is charged or uncharged. Some additional experments have been performed to identify whether the object is charged or uncharged, these experiments with their observations and conclusions drawn are given. Select the option in which conclusion drawn is correct.
