A 2 Ω resistor and a 4 Ω resistor are connected to a cell. [Figure 37.1] Which graph shows how the potential V varies with distance between X and Y?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AGraph showing potential V dropping with a gentler slope, then with a steeper slope, as distance from X increases towards Y.
BGraph showing potential V dropping with a steeper slope, then with a gentler slope, as distance from X increases towards Y.
CGraph showing potential V dropping with a steeper slope, then with a gentler slope, as distance from X increases towards Y.
DGraph showing potential V dropping with a steeper slope, then with a gentler slope, as distance from X increases towards Y.
✓ Correct answer
D: Graph showing potential V dropping with a steeper slope, then with a gentler slope, as distance from X increases towards Y.
