2. Electric Potential and Capacitance
easy

બે વિદ્યુતભારો $2 \;\mu\, C$ અને $-2\; \mu \,C$ એકબીજાથી $6 \,cm$ દૂર આવેલા બિંદુઓ $A$ અને $B$ પર મૂકેલા છે.

$(a)$ તંત્રના કોઈ સમસ્થિતિમાન પૃષ્ઠની ઓળખ કરો.

$(b)$ આ સપાટી પર દરેક બિંદુએ વિદ્યુતક્ષેત્રની દિશા કઈ છે?

Option A
Option B
Option C
Option D

Solution

$(a)$ The situation is represented in the given figure.

An equipotential surface is the plane on which total potential is zero everywhere. This plane is normal to line $AB.$ The plane is located at the mid-point of line $AB$ because the magnitude of charges is the same.

$(b)$ The direction of the electric field at every point on this surface is normal to the plane in the direction of $AB.$
