Question

electric field of 9 ×10 to the power 4 Newton per coulomb is produced by the infinite linear charge at the distance of 2cm.calculate the linear charge density​

Answer 1

Answer:

Explanation:given

E=9×10power 4

R =2cm=0.02m

E=kq/r2

q=Er2/k

q=10power-9

Linear charge density =q/r

=0.5 × 10-7

I think it is correct
