A uniform cube of massand edgemoves on a horizontal surface along the positive-axis, with an initial velocity
Options:
Answer:
C
Solution:
In this case, the force of friction has a tendency to rotate the cube in clockwise direction. So normal reaction will shift in forward direction to balance the torque due to force of friction.
Hence, (During motion, the normal reaction shifts towards positive x-axis from the centre of mass) is correct.
