Answer 2

Answer:

Potential difference between the two point in the given electric field Vb-Va=-Ed

Explanation:

• Let us assume there are two points a and b that are placed at a distance of ‘d’ where “d” is the distance taken parallel to field lines of electric field. The electric field “E” here is considered to be constant.

• The difference between two points a and b is Vb – Va = ∆V the value of this difference will be integration of each point from a to b that gives $-\int E \cdot d s$where negative sign shows that the potential at b is lower than a and since E is constant Vb-Va= -Ed.
