If you double the charge on one of two charged objects, how does the force between them change?

A. Halves

B. Doubles

C. Triples

D. Does not change

E. Quadruples

Force will be doubled.

Explanation:

There exists an electric force between charges and this force is given by :

Here,

k is the electrostatic constant

d is the distance between charges

It is clear that the electric force between charges is directly proportional to the product of charges. According to this question, if the charge is doubled on one of the two objects, the force of between them gets doubled.

Hence, the correct option is (B).

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
