JEE Mains · Physics · STD 11 - 5. work,energy,power and collision
Given below are two statements:
Statement I: An object moves from position \( r_{1} \) to position \( r_{2} \) under a conservative force field \( \vec{F} \). The work done by the force is \( W=-\int_{r_{1}}^{r_{2}}\vec{F}\cdot d\vec{r} \).
Statement II Any object moving from one location to another location can follow infinite number of paths. Therefore, the amount of work done by the object changes with the path it follows for a conservative force.
In the light of above statement, choose the correct answer from the options given below:
- A Both Statement I and Statement II are true
- B Statement I is false but Statement II is true
- C Statement I is true but Statement II is false
- D Both Statement I and Statement II are false
Answer & Solution
Correct Answer
(D) Both Statement I and Statement II are false
Step-by-step Solution
Detailed explanation
Statement-I: Incorrect Correct equation is \( W=\int\vec{F}\cdot d\vec{r} \) Statement-II: Incorrect.
