When two cubes are pressed over each other they unite to form one cube. Which of the following force is responsible for holding them together?

جب ایک دوسرے پر دو کیوب دبائے جاتے ہیں تو وہ ایک مکعب بنانے کے لئے متحد ہوجاتے ہیں۔ مندرجہ ذیل میں سے کون سی قوت ان کو ایک ساتھ رکھنے کی ذمہ دار ہے؟
Explanation
  • When two cubes are pressed together, Van der Waals forces (weak intermolecular forces) help them stick.
  • These forces arise due to temporary dipoles and dispersion forces between molecules.
