An infinite line charge produces a field...

An infinite line charge produces a field of `9xx10^(4) N/C` at a distance of 2cm. Calculate the linear charge density.

Text Solution

Verified by Experts

Use, `E=(lambda)/(2pi epsilon_(0)r)=(2lambda)/(4pi epsilon_(0)r)`
or, `9xx10^(4)(N//C)=(9xx10^(9)xx2lambda)/(0.02)`
`:. Lambda=10-7` coulomb per metre
