The electric field must be zero inside a conductor in electrostatic equilibrium, but not inside an insulator. It turns out that
NISA [10]

Answer:

Explanation:

We shall consider a Gaussian surface inside the insulation in the form of curved wall of a cylinder having radius equal to 3mm and unit length , length being parallel to the axis of wire .

Charge inside the cylinder = 250 x 10⁻⁹ C .

Let E be electric field at the curved surface , perpendicular to surface .

Total electric flux coming out of curved surface

= 2π r x 1 x E

= 2 x 3.14 x 3 x 10⁻³ E

According to Gauss's theorem , total flux coming out

= charge inside / ε ( 250 x 10⁻⁹C  charge will lie inside cylinder )

= 250 x 10⁻⁹ / 2.5 x 8.85 x 10⁻¹²    (  ε = 2.5 ε₀ = 2.5 x 8.85 x 10⁻¹² )

= 11.3 x 10³ weber .

so ,

2 x 3.14 x 3 x 10⁻³ E = 11.3 x 10³

E =  11.3 x 10³ /  2 x 3.14 x 3 x 10⁻³

= .599 x 10⁶ N /C .

What type of image is formed by a lens if m = -1.6?
anastassius [24]

The image formed from the lens is real, inverted and enlarged

Explanation:

The magnification of a lens is given by:

m=\frac{y'}{y}=-\frac{q}{p} (1)

where:

y' is the size of the image

y is the size of the object

q is the distance of the image from the lens

p is the distance of the object from the lens

For this lens, the magnification is

m = -1.6

We notice the following:

- The magnification is negative

- The magnification is larger than 1

Looking at eq.(1), we can therefore make the following conclusions:

- SInce m=\frac{y'}{y} and |m|>1, it follows that |y'|>|y|, so the image is larger than the object

- Since m=\frac{y'}{y} and m, it follows that y' (since y > 0 for convention): this means that the image is inverted

- Since m=-\frac{q}{p} and m, it follows that q>0 (since p > 0 for convention): this means that the image is real
