A point charge q1 = 3.30nC is located on the x-axis at x= 1.90m , and a second point charge q2= -6.40 nC is on the y-axis at y= 1.15 m.

1-)What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1= 0.625m ?

2-)What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r2= 1.40 m?

3)What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r3 = 2.90m ?

0

-723.163841808 Wb

-350.282485876 Wb

Explanation:

= Permittivity of free space =

when r = 0.625 m the charges lie outside the sphere so q = 0

From Gauss law

The electric flux is 0

when r = 1.4

will be inside the sphere

The electric flux is -723.163841808 Wb

when r = 2.9 both charges lie inside the sphere

The electric flux is -350.282485876 Wb

it is because acrylic blanket have acrylic textile fiber

explanation:

its is better than wool blanket

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
