Question
Two hollow conducting spheres have a common center O. The dimensions of the spheres from center O are: A (0.30m), B (0.32m), C (0.89m), D (0.91m). A charge of -290 nC is placed on the inner conductor and a charge of +90 nC is placed on the outer conductor. The inner and outer surfaces of the spheres are respectively denoted by A, B, C, and D, as shown. In Fig. 22.3, the radial component of the electric field, at a point that is 0.25 m from O, is closest to:a)zero
b)-42,000 N/C
c)+29,000 N/C
d)+42,000 N/C
e)-29,000 N/C
Explanation / Answer
ANSWER: a)zero
