If one body is positively charged and another body is negatively charged, free electrons tend to
A. move from the negatively charged body to the postively charged body.
B. move from the postively charged body to the negatively charged body.
C. remain in the negatively charged body.
D. remain in the positively charged body.
A. (if the two bodies are electrically connected)
The correct answer is A. move from the negatively charged body to the positively charged body.
When two bodies have opposite charges, they create an electric field between them. This electric field influences the behavior of electrons in the bodies. Electrons are negatively charged particles that are loosely bound to atoms, meaning they can move relatively easily.
In this scenario, the positive charge on one body attracts and pulls the negatively charged electrons towards it. The negative charge on the other body repels these electrons. As a result, the electrons tend to move from the negatively charged body (where there is an excess of electrons) to the positively charged body (where there is a deficiency of electrons).
To determine this, you need to understand the concept of charges and how they interact. A basic knowledge of electrical forces and the behavior of electrons is necessary to arrive at the correct answer.
