Correct Answer: Option C
Explanation:
- the total energy at any point is a combination of the P.E and K.E
- the sum of PE and KE at any point is always constant not the ratio of P.E to K.E
- the total energy at any point is a combination of the P.E and K.E
- the sum of PE and KE at any point is always constant not the ratio of P.E to K.E
