Explanation:

Answer 2

Explanation:

Given The charge to be put on a spherical conductor of radius 0.2 m to produce an electric field of 0.072 N/C just above its surface is

• So we have
• Electric field E = 1 / 4πεo q / R^2  
• So q = ne, substituting this we get
•                                       E = 1/4πεo ne / R^2
• Now n = E x 4πεo R^2 / e
•             = 0.072 x 1 x 0.2^2 / 9 x 10^9 x 1.6 x 10^-19
•             = 0.00288 / 14.4 x 10^-10
•             n  = 2 x 10^6  
• So the charge q = ne
•                            = 2 x 10^6 x 1.6 x 10^-19
•                            = 32 x 10^-14 C
• So the charge to be put on a spherical conductor is 32 x 10^-14 C
