Question
The figure below two equipotential lines in Xy plane for an electric field. The scales are marked. The X - component Ex and Y - component Ey of the electric field in the space between these equipotential lines are respectively :
Options
A.+ 100 V/m, - 200 V/m
B.+ 200V/m , + 100 V/m
C.- 100 V/m, + 200 V/m
D.- 200 V/m, -100 V/m
Solution
Slope of equipotential lines will be = 1/2
∴ Slope of electric lines must be = - 2
Ex = -
= - 100 V/m
Ey = -
= 200 V/m
∴ Slope of electric lines must be = - 2
Ex = -
= - 100 V/mEy = -
= 200 V/mCreate a free account to view solution
