Which of the following types of objects transmits light without scattering it? *
opaque
transparent
translucent

The transparent objects transmit the light without scattering in it.

Explanation:

Translucent objects: Translucent object allows some light to pass through them. It does not allow light directly to pass through it. It is scattered when the light passes through it. For example, frosted glass.

Opaque objects: Opaque object does not allow light to pass through it. For example, plastic.

Transparent objects: Transparent object allows light to pass through it. It allows light to pass through without scattering. For example, glass.

Therefore, the correct answer is transparent objects.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
