A 10 uc point charge is located at the center of a thin sphericalshell of radius 8.0 m carrying -20 uc distributed uniformly overits surface. [I think unit of distance has been given as uc whichis changed to m]
a.What is the magnitude of the electric field 2.0 cm from the pointcharge?
E = [(9*10^9)*(10*10^-6)]/2^2 = 2.25*10^4 N/C
b.What is the magnitude of the electric field 6.0 cm from the pointcharge?
2.5 *10^3
c.What is the magnitude of the electric field 15 cm from the pointcharge?
E = [(9*10^9)*(-10*10^-6)]/15^2 = - 40 N/C
2)A solid sphere 27 uc in radius carries 22 uc , distributeduniformly throughout its volume.
Find the electric field strength 54 cm from the sphere'scenter.
[(9*10^9)*(-10*10^-6)*(22uc)]/(54)^2=6.79E^-4
