स्थिर विद्युत विभव तथा विभवांतर|वैद्युत द्विध्रुव के कारण विभव|OMR|Summary

A rectangular block of iron has dimension 1.2 cm xx 1.2cm xx 1.5cm . A potential difference is to be applied to the block between parallel sides and in such a way that those sides are equipotential surfaces. What is the resistance of the block if the two parallel sides are (1) the square ends (with dimensions 1.2 cm xx 1.2 cm) and (2) two rectangular sides (with dimensions 1.2cm xx 15cm)?

An infinite changed sheet has 10^(-7) Cm^(-2) surface density of change .How far apart are the equipotential surface differing by 5 voits ? [Hint: Elwctri intensity =rate of fall of potential .]

A solid metallic cuboid measuring 343 cm x 49 cm x 7 cm is melted and converted into cubes with side 7 cm. The sum of the total surface areas ( cm^2 ) of all the cubes is : 343 cm x 49 cm x 7 cm के किसी ठोस धात्विक घनाभ को पिघलाकर 7 cm भुजा वाले घन निर्मित किये जाते है | सभी निर्मित घणो के कुल पृष्ठ क्षेत्रफलों ( cm^2 में) का योग है:

The sketch below shows cross-sections of equipotential surface between two charged conductors that are shown in solid black. Some points one the euquipotential surface near the conductors are marked as A, B, C ………. The arrangement lies in air. ["Take " in_(0)=8.85xx10^(-12) C^(2)//N m^(2)] How much work is required to slowly move a -1 mu C charge from E to D?

The radius and height of a cone are 20 cm and 21 cm respectively. The total surface area (cm^2) of the cone is : किसी शंकु की त्रिज्या 20 cm तथा ऊंचाई 21 cm है, शंकु का कुल पृष्ठ क्षेत्रफल ( cm^2 में) है: (pi=22/7)
