Acceleration Of Block On Smooth Inclined Plane - Practice Questions & MCQ

Two fixed frictionless inclined planes making an angle 30° and 60° with the vertical are shown in the figure. Two blocks A and B are placed on the two planes. What is the relative vertical acceleration of A with respect to B?

In the figure shown the acceleration of A is ${\overrightarrow{a}}_A=15i+15j$ then the acceleration of $B$ is: (A remains in contact with B)

For no friction to act on a block kept on an accelerating wedge as shown in figure, acceleration of the wedge should be

in above case, what is  Component of acceleration along y or perpendicular to  inclined plane?

The system shown in figure are in equilibrium . What is the reading of spring balance . (g = 10 m/s ²)
