A charged conducting sphere of radius 10.0 cm is surrounded by an electric field as shown. a. If the field strength at the surface of the sphere is 6.00 X 10 N/C, what is the charge on the sphere? b. What type of charge is on the sphere? c. What is the flux value at the surface of the sphere? d. What is the flux value 25.0 em. from the sphere?Explanation / Answer
(a)
Electric field is fiven by:
E = kq/r2
=> q = Er2/k
=> q = (6*104)(0.10m)2/(9*109)
= 6.67 x 10-8 C
(b)
Since the field is diverging, the charge is positive.
(c)
Flux phi = EA= (6*104)(4*pi*0.12)
= 7539.82 Vm
(d)
phi = (6*104)(4*pi*0.252)
= 47,123.88 Vm
