Question

Force acting on a particle moving in the $x-y$ plane is $\vec{F}=\left(y^{2} \hat{i}+x \hat{j}\right) N , x$ and $y$ are in metre. As shown in figure, the particle moves from the origin $O$ to point $A(6 m , 6 m )$. The figure shows three paths, $O L A, O M A$, and $O A$ for the motion of the particle from $O$ to $A$.

Along which of the three paths is the work done maximum?

• A. O A
• B. O M A
• C. OLA
• D. Work done has the same value for all the three paths.

Answer 1

Answer: (B)

Correct answer is (b) O M A
