The rod is inside a cylindrical shell of radius b 22.2 mm and linear charge density A2 5.80 nC/m What is the magnitude of the electric field at a radial distance of 17.5 mm from the centre? Submit Answer Incorrect. Tries 2/10 Previous Tries What is the direction of the electric field at 17.5 mm? Incorrect Inward Correct: Outward You are correct. Previams Tries 8:05 PM 2/27/2016Explanation / Answer
Here ,
a = 5.4 mm
lamda1 = 8.90 nC/m
lamda2 = - 5.80 nC/m
at a distance ,d = 17.5 mm
inside the second shell , the electric field due to second shell is zero
electric field = 2 * k * lamda1/d
electric field = 9*10^9 * 8.9 *10^-9/0.175
electric field = 915.4 N/C
the electric field is 915.4 N/C
the direction of electric field will be radially outwards
