Question

compare the force of attraction between the iron, rubber, chalk

Answer 1

iron is strongest then chalk and rubbed

Answer 2

hey bruh it's a nice question , Ur ans is here firstly iron has comparatively more inter molecular force since it is solid , and hence it is difficult to separate the closely packed particles, where as rubber is also solid and even it has inter particle force but it is less than as of iron , and hence it is easy to break the rubber , and where as chalk has all.similar properties mentioned above but it has comparatively less particle force as that of iron ore rubber and hence it is to easy to break the chalk.
