Passage V
Students studied electric forces between charged spheres using the apparatus shown in Figure 1.
In each trial, the students mounted 2 uncharged conducting spheres D cm apart on the stands. Then they placed a negative charge on each sphere. The electric force between the spheres caused Stand 2's sphere to move away from Stand 1's sphere, thereby twisting the vertical wire clockwise (see Figure 2).
The students twisted the wire counterclockwise until Stand 2's sphere had moved back to its original position. The angle through which they twisted the wire,
28. The results of Study 2 are best represented by which of the following graphs?
Your Answer is
Correct Answer is G
Explanation
Looking at table 2, when the charge of B increases, θ decreases, but the curves in F, H, and J options are all increasing or flat, so we can only choose G< /p>
