Q 1 :    

A wheel is rolling on a plane surface. The speed of a particle on the highest point of the rim in 8 m/s. The speed of the particle on the rim of the wheel at the same level as the centre of wheel, will be:         [2025]

  • 42 m/s

     

  • 8 m/s

     

  • 4 m/s

     

  • 82 m/s

     

(1)

If VB=2V

Point A is instantaneous centre of rotation

Given, VB=8 m/s  V=4 m/s

VP=2V  VP=42m/s
