Because it is acted upon by balanced forces.
Toy cars use a variety of mechanisms to make them go, but they all store up potential energy. Although the elastic material inside is usually steel and not rubber, the principle is the same. By changing the shape of the material (usually a coil of metal) energy is stored and then released as motion.
The charge on the left sphere negatively charged.
<h3 /><h3>What is charge?</h3>
Due to the physical property of electric charge, charged material experiences a force when it is subjected to an electromagnetic field. You might be electrically positive or negative. While similar charges repel one another, opposite charges attract.
In order for the neutral metal sphere and negatively charged metal rod to have the same potential, some negative charge must flow from the rod to the sphere in order for them to both have negative charges.
The sum of the negative charges in them would be equal to the initial negative charge in the rod since the entire charge is preserved.
