It becomes possible to define potential at a point in an electric field because electric field
1 is a conservative field
2 is a non-conservative field
3 is a vector field
4 : obeys principle of superposition
Explanation:
(a) Potential energy is defined only in case of conservative forces like electrostatic force \{and due to which electrostatic field is a conservative field). It is not defined for non-conservative forces like friction

Which of the following about potential at a point due to a given point charge is true?
The potential at a point \(P\) due to a given point charge
1 is a function of distance from the point charge.
2 varies inversely as the square of distance from the point charge.
3 is a vector quantity
4 is directly proportional to the square of distance from the point charge.
Explanation:
(a) Since \(V=\frac{1}{4 \pi \varepsilon_0} \frac{q}{T}\), for a given point charge, \(q\) is constant, therefore \(V\) depends only on \(r\). Hence \(V\) is a function of distance.
