We divide the thin rectangular sheet in small parts of height b and length dr. All these sheets are parallel to b. The infinitesimal moment of inertia of one of these small parts is
where
Now we find the moment of inertia by integrating from
to
The moment of inertia is
(from (-a/2) to
(a/2))

Electroscope is the instrument that has the ability to detect the presence of an electric charge. Although electroscope has the power to measure the amount of charge, but for a perfect measurement the electrometer is used. Around the year 1600, electroscope was discovered by William Gilbert he British physician. This is a pretty primitive but highly effective instrument in regards to detecting the presence of electric charges. Two basic but effective electroscopes are the gold-leaf electroscope and the pith-ball electroscope.
Боже, как это сложно! Ну ладно.
Между прочим это ты сам должен делать, а то не куда не поступишь!
