A rigid triangular body, PQR, with sides of equal length of 1 unit moves on a flat plane. At the
instant shown, edge QR is parallel to the x-axis, and the body moves such that velocities of
points P and R are VP and VR, in the x and y directions, respectively. The magnitude of the
angular velocity of the body is
  • a)
  • b)
  • c)
    2VR
  • d)
    2VP
Correct answer is option 'C'. Can you explain this answer?

The given body is a rigid body; Hence the given body will not have any deformation, and the possible motion is translation and angular motion. we know that the angular motion of the object is
always defined as the motion about the point. Hence, first we have to find a point parallel to both
velocity VP and VR.

∴ Angular velocity,
