Step 1
Which diagram shows lines of equipotential in steps of equal potential difference near an isolated point charge?
Answer
The correct diagram representing lines of equipotential near an isolated point charge is diagram D.
In electrostatics, equipotential lines are surfaces where the electric potential is the same. For a point charge, these lines are concentric circles surrounding the charge, demonstrating that the potential difference between each circle remains constant as you move away from the charge. Other options, such as A, B, and C, do not illustrate this characteristic.
Thus, the answer is option D.
