4.

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

 [A]. 2.0 cm [B]. 1.5 cm [C]. 1.0 [D]. 0.5 cm.

Explanation:

No answer description available for this question.

 Rajesh Thakur said: (Dec 10, 2016) On x - axis, X= R * 3 -r * 3/R * 2 - r * 2 = 3 * 3 - 1.5 * 3/3 * 3 - 1.5 * 2 = 3.5cm, Hence distance of centre of gravity of remainder from centre of circle. 3.5 - 3 = 0.5.

 Pavan B said: (Dec 11, 2017) r/R = 1.5/3.0 = 0.5. So, C.G of the circle acts on the center of a circle.

 Bhoopender Chauhan said: (Jan 5, 2018) C.g of reminder from centre is R/6. And from end is 7R/6, So a/q. From centre of plate R/6=3/6=.5

 Avinash said: (Jan 21, 2019) 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. Circle centre at 3 so; 3-2.5= 0.5 is the answer.

 Lalan Kumar said: (Sep 28, 2019) R/D = cg. 3/6 = .5.

 Swapnalatha said: (Jul 18, 2020) R/D = 3/6 = 0.5.
