Question

A uniformed charged sphere has a total charge of 300 microcoulomb and a radius of 8cm. Find the electric field intensity at:
a. a point 6cm from the center of the sphere
b. a point on the surface of a sphere
c. a point inside the surface​

Answer 1

Answer:

pls mark as brainliest it took a lot of time

Explanation:

a) electric field inside non conducting sphere is = 0

   therefore force on charge q = qt

                                                     q*0 = 0

b) electric field due to sphere = E1 = 0

• electric field due to this charge = E2 = 1/4$\pi$E * q/r^2

• so electric field at center of sphere is

• Enet = 1/4$\pi$E * q/r^2

c) electric field due to charge of sphere on b

• E1 (in direction) = 1/4$\pi$E * q/r^2 e^n

• E2 (in direction) = 1/4$\pi$E * q/r^2 e^n

• Enet = E1+E2

          1/4$\pi$E * q/r^2 e^n  +   1/4$\pi$E * q/r^2 e^n.
