Class 11PhysicsWork, Energy, Power and CollisionWork Energy Theorem and Conservation of Mechanical Energy
MediumAs shown in the figure,a particle of mass $10 \ kg$ is placed at a point $A$. When the particle is slightly displaced to its right,it starts moving and reaches the point $B$. The speed of the particle at $B$ is $x \ m/s$. (Take $g = 10 \ m/s^2$). The value of $x$ to the nearest integer is:
- A$5$
- B$8$
- C$12$
- D$10$
