Answer:
Electric force results form mutual interactions between two charges.
The answer is A) Recycling. Recycling has to do with finding something valuable amongst trash. For example, in a dumpster, someone may just find a nice painting. Mark as brainliest :)
The new rotational energy of the system(RE) = 
How this is calculated?
- Distance of each astronaut from centre of mass(m)=d/2
- Moment of inertia of system

- So, angular speed,ω =
=
- Rotational energy of system=

where, ω= angular speed

What is rotational energy?
- Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
- Looking at rotational energy separately around an object's axis of rotation, the following dependence on the object's moment of inertia is observed
