Question

An object comprises of a uniform ring of radius

R

and its uniform chord

A B

(not necessarily made of the same material) as shown. Which of the following can not be the centre of mass of the object :

Since the chord is a uniform chord and the center of mass coordinate of system will be displaced in x and y coordinate by same value- Hence X and Y coordinate will be same - So the wrong aption is -R3-R2-xA0-

An object comprises of a uniform ring of radius $R$ and its uniform chord $A B$ (not necessarily made of the same material) as shown. Which of the following can not be the centre of mass of the object :

$(R / 4, R / 4)$
$(R / 3, R / 3)$
$(R / 3, R / 2)$
$(R / \sqrt{2}, R / \sqrt{2})$

Since the chord is a uniform chord and the center of mass coordinate of system will be displaced in x and y coordinate by same value. Hence X and Y coordinate will be same . So the wrong aption is $(\frac{R}{3}, \frac{R}{2})$

An object comprises of a uniform ring of radius R and its uniform chord AB (not necessarily made of the same material) as shown. Which of the following can not be the centre of mass of the object :(R/4,R/4)(R/3,R/3)(R/3,R/2)(R/√2,R/√2)

Since the chord is a uniform chord and the center of mass coordinate of system will be displaced in x and y coordinate by same value. Hence X and Y coordinate will be same . So the wrong aption is (R3,R2)
