Answer:
Charge on the sphere will be equal to
Explanation:
We have given radius of the sphere a = 13 cm
And electric filed 21 cm from the center is
So distance from the center r = 21 cm
We have to find the charge on the sphere
As
So according to Gauss law electric field is equal to
So
So charge on the sphere will be equal to
Answer:
A) the objects attract each other
Explanation:
gravity always pulls no matter what. it does not repel
This sequence is called the electromagnetic spectrum. This spectrum highlights or shows the arrangement of electromagnetic waves in order of frequency and wavelength. Electromagnetic waves are waves that have both an electric and magnetic component or fields. These waves do not require a medium to exist. Examples include visible light, microwaves and gamma rays. <span />
