My calculations are as follows:
I went on the assumption, having read it somewhere, that the electric field within a metallic sphere have 0 magnitude. and wrote E=0
and secondly 2) E= (9*10^9)(-10*10^-6)/ (0,6^2)= 32364 N/C
Though the key says these answers are incorrect , is this so or is...
Electrostatic force problems, help urgent!
Homework Statement
Question: An isolated hollow metal sphere of radius 40 cm carries a charge of -10*10^-6.
What is the magnitude of the electric field E (a) in the empty space inside the sphere and (b) 60 cm from the center of the sphere ( no...
