Two point masses of 0.3 kg and 0.7 kg

Asked by admin @ 16/08/2021 in Physics viewed by 281 People

Two point masses of 0.3 kg and 0.7 kg are fixed at the end of rod of length 1.4m and of negligible mass. The rod is set rotating about an axis perpendicular to it's length with a uniform angular speed. The point on the rod through which the axis should pass in order that the work required for rotation of the rod is minimum is located at a distance of?
