Q. No.If \(E\) and \(V\) are electric field and electric potential respectively due to a point charge, then which of the following graphs best represents their variation?
| 1. |  |
2. |  |
| 3. |  |
4. |  |
Subtopic: Â Relation between Field & Potential |
Level 4: Below 35%
Hints
The electric field (\(E\)) and potential (\(V\)) due to the field are related as \(E=-\dfrac{dV}{dr}\). For the \(V\) vs \(r\) graph shown, identify the correct \(E\) vs \(r\) graph:
| 1. |  |
2. |  |
| 3. |  |
4. |  |
Subtopic: Â Relation between Field & Potential |
Level 3: 35%-60%
Hints
The variation of potential with distance \(R\) from a fixed point is shown in the figure. The electric field at \(R=5~\text{m}\) is:
(Given, the potential, \(V\) in volts and distance, \(R\) in meters)
(Given, the potential, \(V\) in volts and distance, \(R\) in meters)
| 1. | \(2.5~\text{Vm}^{-1}\) | 2. | \(-2.5~\text{Vm}^{-1}\) |
| 3. | \(\dfrac{2}{5}~\text{Vm}^{-1}\) | 4. | \(-\dfrac{2}{5}~\text{Vm}^{-1}\) |
