A conducting spherical shell of inner radius 4.00 cm and outer radius 5.00 cm is concentric with the solid sphere and has a charge of-3.40 . Find the electric field at the following radii from the center of this charge configuration. (a) r= 1.00 cm N/C direction The magnitude is zero. ’ (b) r= 3.00 cm magnitude 8730288889N/C direction radially outward (c) r-4.50 cm N/C magnitude o direction The magnitade is zaro d) r= 7.00 cm IR..

Explanation / Answer

12.

The Tension in the wire is determined by force of repulsion between the spheres.

T=FE =KQ1Q2/r2

T=K*(Q/2)*(Q/2)/(L+2R)2

T=(9*109)(54*10-6)2/4*(2.1+2*0.005)2

T=1.47 N
