Q1: From a circular plate of a diameter 6 cm is cut out a circle whose diameter is equal to the radius of the plate. The C.G. of the remainder from the centre of circular plate is at a distance of

ANS:D - 0.5 cm.

X = 5R/6.
= 5(3)/6,
=2.5.

X is the distance of the centroid from the end in the question he asked distance of the centroid from centre.
