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,
26. Suppose that in Study 3 an additional trial had been performed with Sphere A mounted on Stand 1 and Sphere H, a sphere of radius 0.70 cm, mounted on Stand 2. Based on the results of Study 3,
Your Answer is
Correct Answer is H
Explanation
According to table 3, it can be seen that when the radius of another sphere is smaller, the θ is also smaller. The radius of Sphere H is 0.70 cm, which is between spheres F & E. So at this time θ is also between 8-11
