Question

The electric field intensity at all points in space is given by `vecE = sqrt(3)hati - hatj` volts//metre. The nature of equipotential lines is x-y plane is given by
A.
B.
C.
D.

Answer 1

Correct Answer - C
The direction of uniform electric field E in xy-plane is as shown in figure 1

The equipotential lines will be perpendicular to electric field, Also electric field points from high potential region towards low potential region. Therefore nature of equipotential in x-y plane is given by figure 2.
