Question

if an electric charge of 32 micro coulumb is residing on a spherical conductor of radius 8cm , then its surface charge density in micro coulumb/cm² is___
a. 1/8π
b. 1/4π
c. 4π
d. 8π​

Answer 1

Answer:

may be b. 1 /4 π is the correct answer

Answer 2

Answer:

surface charge density (d) is = charge per unit area

Explanation:

d= Q/A

d= 32/ 4πR^2

d= 1/8π
