Why is no real body truly rigid?
AReal bodies deform
BReal bodies dissolve
CReal bodies dislodge
DReal bodies disperse
Answer & Solution
Correct answer: A. Real bodies deform
1. Rigidity is an idealisation, not an observed fact.
2. Applying a force always changes a real shape a little.
3. No real body is truly rigid, since real bodies deform under the influence of forces.
4. So the answer is real bodies deform.
