Consider the following two statements Statement 1: A body of weight W falls from a height h and strikes the ground. If the body starts from rest, the velocity with which it strikes the ground is ඥ2𝑔𝑔ℎ , where g is the acceleration due to gravity. Statement 2: If the same body (initially at rest) slides without friction along an inclined plane PQ (angle of inclination α) starting from an elevation h above point Q, then its velocity at point Q is ඥ2𝑔𝑔ℎ The correct option is
- A. Both statements 1 and 2 are true
- B. Statement 1 is true and 2 is false
- C. Statement 1 is false and 2 is true
- D. Both statements 1 and 2 are false W h h P Q W α XE (GATE 2014)
