A positive charge is placed in an electric field that points west. the direction of the force on the positive particle point toward the west.
Due to the physical characteristic of electric charge, charged material experiences a force when it is exposed to an electromagnetic field. Electric charges can be positive or negative (commonly carried by protons and electrons respectively). While like charges repel one another, opposite charges attract. If an object has no net charge, we refer to it as neutral.
The charge on one electron is -1.6 ×10⁻¹⁹ coulomb.
As given in the problem statement when a positive charge is placed in an electric field that points west. the direction of the force on the positive particle will also point toward the west because for a positively charged
particle the direction of the electric field is the same as the force.
Thus, a positive charge is introduced into a westward-pointing electric field. the force acting on the positive particle points westward

Explanation:
Asteroids are irregular sized and shaped rocky bodies -very small as compared to a planet which revolve around the sun in elliptical orbit. In the solar system, majority of the asteroids can be found in the asteroid belt which lies between the orbits of Mars and Jupiter. It is thought to be the debris of an unformed planet due to large gravity of Jupiter. Examples of asteroids - Ceres, Vesta, Eros etc.

Classifying reactions as endothermic or exothermic depends on the comparison of energy required to break bonds in the reactants and energy released when new bonds are formed in products. Bond formation generally releases energy and is exothermic, while bond breaking absorbs energy and is endothermic. Therefore, reactions which make more or stronger bonds (AB+C-->AC+B, A2+C2-->2AC, A2+B2-->2AB) are likely exothermic, whilst those breaking more or stronger bonds (B2+C2-->2BC, A+BC-->AB+C) are likely endothermic.
Chemical reactions can be classified as endothermic if energy (usually in the form of heat) is absorbed from the surroundings, or exothermic if energy is released into the surroundings. The key here lies in understanding the concept of bond energy. Essentially, if more energy is required to break the bonds in the reactants than is released when new bonds are formed in the products, the reaction is endothermic. Conversely, a reaction is exothermic if less energy is required to break the bonds in the reactants than is released when new bonds are formed in the products.
Without exact bond energies, we can only hypothesize about the reactions. However, the general rule is that bond formation is exothermic while bond breaking is endothermic. Therefore, any reaction that results in the formation of more or stronger bonds than it breaks would likely be an exothermic reaction (AB+C-->AC+B, A2+C2-->2AC, A2+B2-->2AB). On the other hand, a reaction that requires breaking more or stronger bonds than it forms (B2+C2-->2BC, A+BC-->AB+C) would likely be endothermic.
