Question

Sphere is placed between two smooth wedges, and wedges are given velocities as shown in the diagram. Velocity of centre of sphere in vertica direction will be 10 m/s 532 (1) 10 m/s (3) 15 m/s (2) 5 m/s (4) 20 m/s.​

Answer 1

Velocity of the center  of the sphere = 20m/s * slope of the wedge.

Explanation:

Given: Sphere is placed between two smooth wedges, and wedges are given velocities as shown.

Find: Velocity of the center of sphere in vertical direction.

Solution:

We can observe that the wedge is a tangent to the sphere. The tangent touches the sphere at a height R/5 where R is the radius. Using this information, we can solve to find the slope of the wedge.

The velocity of the center of the sphere will be 20m/s * slope of the wedge.
