If one body is positively charged and another one is negatively charged free electrons tend to ?
lord [1]

Answer is: Move from the negatively charged body to the positively charged body.

The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.

The proton (p⁺) is subatomic particle with a positive electric charge of +1e elementary charge.

Opposite charges (positive and negative) attract one another.  

The negatively charged body has extra electrons, more electrons than protons.

The positively charged body has less electrons than protons.
