This question has Statement $-1$ and Statement $-2$ Of the four choices given after the Statements, choose the one that best describes the two Statements
Statement $1$ : No work is required to be done to move a test charge between any two points on an equipotential surface
Statement $2$ : Electric lines of force at the equipotential surfaces are mutually perpendicular to each other
Statement $1$ is true, Statement $2$ is true,
Statement $2$ is the correct explanation of Statement $1$
Statement $1$ is true, Statement $2$ is true,
Statement $2$ is not the correct explanation of Statement $1$
Statement $1$ is true, Statement $2$ is false
Statement $1$ is false, Statement $2$ is true
Equipotential surfaces associated with an electric field which is increasing in magnitude along the $x$-direction are
Figure shows a set of equipotential surfaces. The magnitude and direction of electric field that exists in the region is .........
Given below are two statements: one is labelled a
Assertion $(A)$ and the other is labelled as Reason$(R)$
$Assertion$ $(A)$ : Work done by electric field on moving a positive charge on an equipotential surface is always zero.
$Reason$ $(R)$ : Electric lines of forces are always perpendicular to equipotential surfaces.
In the light of the above statements, choose the most appropriate answer from the options given below
If a unit positive charge is taken from one point to another over an equipotential surface, then
What is an equipotential surface ? Draw an equipotential surfaces for a
$(1)$ single point charge
$(2)$ charge $+ \mathrm{q}$ and $- \mathrm{q}$ at few distance (dipole)
$(3)$ two $+ \mathrm{q}$ charges at few distance
$(4)$ uniform electric field.
