Question

An infinitely long thin straight wire has uniform linear charge density of then, the magnitude of the electric intensity at a point 18 cm away is: (given )

Answer 1

Answer:

for a infinite long straight wire , the electric field at 18cm is given by

q/(2*pi*e0*r)

where

q= charge density

e0= 8.85*10^-12 C^2/N.m^2

r= 18 cm
