I'm trying to create this halftone effect in Inkscape but I'm not able to produce it. All I'm able to do is create a small circle and clone it to produce simple halftone. But how do I do this?

To quickly create the desired image we can use the Clone > Create Tiled Clones... tool.
Here is the steps involved (in Symmetry: P1: simple translation mode):
Draw a circle of desired size (e.g. 400 px)
Set fill to nothing
Set Stroke
Paint to fully transparent (here I used light blue for demonstration
Style to Mid Marker DotL (dot size depends on stroke width!)
Choose Clone > Create tiled clone with the following settings:
Rows, Columns 1 x 10 (for 10 clones)
Shift x: -100% (to keep clones centered)
Rotation per columns 10°
Select all or create a group.
Choose Clone > Create tiled clone with the following settings:
Rows, Columns 1 x 10
Shift x: -100%
Scale X (per column): -10%
Scale Y (per column): -10%
By choosing different settings we may change number or color of dots, rotation, or introduce a fade effect if needed.
For changing colors of the dots we have to apply Extensions > Modify Path > Color Markers to match Stroke in step 1. above before we make the stroke transparent.
Additionally in the next example a Fade Out of 10 % in Blur & Opacity and a rotation of 5° was added when creating the clones in step 6.
This would be easier with Illustrator's Transform Effect, but with Inkscape I believe you can only emulate that by combining Duplicate and Transform.
You can create rings of dots by using a rotation transform. Offset the center of rotation of a dot, duplicate it, and apply a Rotation Transform. The angle of rotation will be defined by the number of desired dots in the circle divided by 360.
You can use the same technique to quickly create multiple rings. This is not quite exactly the same as your posted graphic because it will result in the same number of dots per ring, but this will help illustrate how to use transform and duplicate together:
Start with a ring like this, select it:
Duplicate it via Edit → Duplicate or by pressing Ctrl + D
Apply a Scale Transform via Object → Transform
Repeat until happy:
