A rod of length 1.4 m and negligible mass has two masses of 0.3kg and 0.7 kg tied to its two ends. Find the location of the point on this rod, where the rotational energy in minimum, the when the rod is rotated about the point.

Options

A. 0.98 m from 0.3kg
B. 0.98 m from the 0.7 kg
C. 0.7m from 0.3 kg
D. 0.7 m from 0.7kg
