Embibe Experts Solutions for Exercise 4: EXERCISE 1.4

A region of space contains a constant electric field of magnitude, $1325 \mathrm{N} {\mathrm{C}}^{-1}$. A wire frame forming a square, $0.27 \mathrm{m}$ on a side, is placed in the region, oriented so that the perpendicular to the plane of the square makes an angle of $48°$ with the field. What is the magnitude of the electric flux through the frame?

A charge $q$ is placed just above the centre of a horizontal circle of radius $r$, and a hemisphere of this radius is erected about the charge. Compute the electric flux through the closed surface that consists of the hemisphere and the planar circle. Do not use Gauss' law.

Which one of the following is correct regarding order of electric field intensity?

A hemispherical surface of radius $R$ is located in a uniform electric field $E$, as shown. The flux of electric field through the surface is

A cylinder of height  $H$ ' and radius of cross-section $r$ ' is kept in uniform electric field $\overrightarrow{E}$ as shown in figure. The magnitude of flux that enters from left half of cylinder is
