Question

Half of the ring is uniformly positively charged and other half uniformly negatively charged.
The electric field at the centre is
(1) directed upward
(3) zero
(2) directed downward
(4) directed horizontally​

Answer 1

Answer:

As net charge is Zero

From Equation F=qE

As q=0

E = 0

Therefore Option 2 is correct

Answer 2

Concept Introduction:-

A physical field surrounding particles with an electric charge, exerting a all in the field other charged particles are subjected to this force, either positively or negatively repelling or attracting them, is known to as an electric field.

Explanation:-

We have been provided a question

We need to choose from the given alternatives the correct option

The correct option is $(3)$ zero

It is because the electric field at the center is zero. The electric field point away from positive charges and towards negative ones.

Final Answer:-

The correct answer is option $(3)$ zero
