Expert Answer:

Figure shows the arrangement of three 10 g masses placed at the corners of equilateral triangle of side 5 cm.
 
Since the axis of rotation is passing through one corner where a 10 g mass is placed,
only other two masses are contributing for moment of inertia of the system.
 
Moment of inertia = 2×10×10-3 × 52 × 10-4 = 5×10-5 kg-m2
