Two rings of radius 5 cm are 16 cm apart and concentric with a common horizontal axis. The ring on the left carries a uniformly distributed charge of 37 nC and the ring on the right carries a uniformly distributed charge of 37 nC. What is the magnitude and direction of the electric field on the axis halfway between the two rings?

Respuesta :

Answer:

Electric field =zero.

Explanation:

since both the rings are similar having same charge distribution so at a point midway between the two, electric field will be same in magnitude but opposite in direction .Therefore they will cancel out each other. hence resultant electric field will be zero.
