Charge of uniform density (20 nC/m?) is distributed over a cylindrical surface
(radius -1.0 cm), and a second coaxial surface (radius = 3.0 cm) carries a uniform charge
density of -12 nC/m2. Determine the magnitude of the electric field at a point 4.0 cm from
the symmetry axis of the two surfaces.

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.
