A ball (initially at rest) is released from the top of a tower. The ratio of work done by the force of gravity, in the first, second and third seconds is
- A \(1: 3: 5\)
- B \(1: 4: 16\)
- C \(1: 9: 25\)
- D \(1: 2: 3\)
Answer & Solution
Correct Answer
(A) \(1: 3: 5\)
Step-by-step Solution
Detailed explanation
Work done by the force of gravity is directly proportional to the distance travel in \(n\)th second. \[ W \propto S_n \] \(\therefore\) Ratio of work done by the force is \(1: 3: 5\).
