The spinning of the Diwali cracker 'ground chakkar' involves the concept of
- A Conservation of mechanical energy
- B Conservation of linear momentum
- C Conservation of angular momentum
- D Conservation of charge
Answer & Solution
Correct Answer
(C) Conservation of angular momentum
Step-by-step Solution
Detailed explanation
The torque acting on the "ground chakkar" is zero. Torque is given by: \(\tau=\frac{\mathrm{dL}}{\mathrm{dt}}=0\). \(\therefore \mathrm{L}=\) constant Hence the phenomenon is based on law of conservation of angular momentum.
