Select the forces which are basically electrical in nature.
A. Forces that hold the molecules together in a solid.
B. Adhesive force of glue
C. Forces associated with surface tension
D. Forces that hold atoms together in a solid
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A, B, C and D
Apart from gravity (and the nuclear forces that act only inside nuclei), the everyday forces between pieces of matter arise from electric forces between the charged particles (electrons and nuclei) of atoms and molecules.
(A) Forces that hold the molecules together in a solid. — Correct. These intermolecular forces are electric attractions between the charge distributions of neighbouring molecules.
(B) Adhesive force of glue — Correct. Adhesion is the intermolecular attraction between the glue and the surface, which is electric in origin.
(C) Forces associated with surface tension — Correct. Surface tension comes from the cohesive intermolecular forces at a liquid surface, again electric in origin.
(D) Forces that hold atoms together in a solid — Correct. Ionic, covalent and metallic bonds are all electric attractions between electrons and nuclei.
NCERT (2026-27):
Electric Charge – “… Forces that hold the molecules together, forces that hold atoms together in a solid, the adhesive force of glue, forces associated with surface tension, all are basically electrical in nature, arising from the forces between charged particles.”
