If `W_(1) W_(2)` and `W_(3)` represent the work done in moving a particle from `A` to `B` along three different paths `1.2` and`3` respectively (asshown ) in the gravitational fieled of a point mass m, find the correct relation between ` `W_(1) W_(2)` and `W_(3)` A. `W_(1)=W_(2)=W_(3)`B. `W_(1)gt W_(2)gt W_(3)`C. `W_(1)=W_(2)gt W_(3)`D. `W_(1)lt W_(2)lt W_(3)` |
Answer» Correct Answer - A Since gravitational force is conservative so, work done will independent of path Therefore `w_(1)=w_(2)=w_(3)` |
