A disc of radius '

r

' is removed from the disc of radius '

R

' then
a) The minimum shift in centre of mass is zero
b) The maximum shift in centre of mass cannot be greater than

r^2 /(R+r)

c) Centre of mass must lie where mass exists
d) The shift in centre of mass is

r^2 /(R+r)

View answer and explanation

Correct option: A

Only a and b are correct

Option A (Only a and b are correct) is correct because the minimum shift in the center of mass is zero, and the maximum shift cannot be greater than

r^2/(R+r)

.
